Olympic champion Nicola Adams is guaranteed at least a bronze medal after reaching the semi-finals of the women's flyweight competition at the Rio Olympics.
The 33-year-old Leeds boxer has already secured another medal after picking up a unanimous decision win in her opening bout and will next face Cancan Ren, the Chinese opponent she defeated in the London 2012 final.
Adams benefited from a bye in the opening round, but was made to work for a quarter-final win over Ukrainian Tetyana Kob as she emerged victorious with scores of 39-37 39-37 and 40-36.
During a scrappy contest, Adam offered the cleaner work with her accurate right hand, although she was forced to withstand a late assault from Kob.

Adams, who was the final Team GB boxer to appear at the Games, told theBBC: "It's a massive difference.
"Once you get that first fight out of the way, you get the ring rust off and get a feel for the ring. It was just nice to get that one out of the way - and I've sealed a medal.
"I wasn't at my best in there but I am sure to improve as the days go on.
"I've been so eager to get in the ring. I've been watching the lads going out boxing, I've watched Savannah [Marshall] go out and box and all I've wanted to do is get in the ring."
Britain's Jack Burnell was left fuming and perplexed after being disqualified from the men's open water swimming when in medal contention.
The 23-year-old was in the mix at the end of the 10-kilometres race but was denied in the frantic finale.
Initially he was in a photo finish for third, behind winner Ferry Weertman of Holland, before being demoted to fifth and then disqualified altogether for a second caution from race officials.
The Loughborough swimmer, who was fifth in last year's World Championships, said: "It was an absolute joke, the whole thing from start to finish.
"You've got the best guys in the world out here, who have trained for four years, put a lot of hard work into this.
"This is the pinnacle of our sport and it's ruined by a couple of judges who want to stick their nose in, just because they want something to do.

"They want to be seen to be like they're doing something. Just let the guys race. It's an absolute outrage.
"There were yellow cards left, right and centre. The first yellow card I got, there was nobody either side of me.
"I couldn't physically have touched anybody, even if I had had six-foot long arms. And he gives me a yellow card.
"I just laughed at the guy as I was swimming. I looked at him and shook my head. He just nodded his head and showed me the yellow card. They just want to be seen to be doing something.
"This is unbelievable, considering how much work these guys put in, for four years, including myself - and it all gets thrown away just by some judge who wants to stick his oar in."
Burnell was furious after the race finished, describing his disqualification as a "joke"
Open water swimming is notoriously rough and often sees tugs of limbs, clashes of elbows and the occasional punch.
Weertman won gold in one hour, 52 minutes and 59.8 seconds. Greece's Spiros Gianniotis was second in the same time and Burnell was one of three swimmers just 2.42 seconds behind them.
France's Mac-Antoine Olivier was ultimately awarded bronze ahead of Zu Lijun of China, with Burnell left empty handed.
Defending Olympic champion Oussama Mellouli of Tunisia was 12th, 6.3secs behind, despite Burnell alleging he impeded his progress.

The Brit added: "The guy that should've got disqualified is the guy that stopped me, Mellouli. He grabbed my leg.
"He was holding my leg not for one, two, three, but for four or five strokes, so I had to turn round to try to get him off. What am I meant to do?
"In that line, I'm thinking 'this is brilliant, this is perfect for me'. We're all at top speed and I'm stopped dead. I'm one of the fastest finishers in there.
"He was yellow carded for that, which stopped me winning, but I was disqualified for trying to get him off to try to win the race. Explain that to me. Absolutely outrageous.
"There's an appeals process, but it will mean nothing. It's never changed anything in the sport.

"Imagine this happens in the (football) World Cup final and the referee gives the goalie a yellow card for standing there. That is how ridiculous this is.
"A referee should not be there unless there is something clearly wrong. They always want to be seen to be doing something.
"On the Olympic stage, what do they want to do? Do they want to get on telly to show a yellow card? To show their family back home that they're doing something? It's absolutely ridiculous."
Usain Bolt began the latest leg of his 'triple triple' bid with the easiest of victories in his 200m heat in Rio.
The Jamaican already has the 100m title in the bag as he aims to win three sprint golds for the third successive Olympics, and he finished at jogging pace on his way to first place in the ninth of 10 200m heats on Tuesday.
Bolt's time of 20.28 seconds was more than a second slower than the 19.19 world record he has his sights on beating by the time the event ends on Thursday.
But he said afterwards: "I didn't really run that hard. I know how to run a 200m. Tomorrow [in the semi-finals] I will show much better progress because I will have to run faster, so I'm looking forward to that.
"Most of the young guys always run fast in the heats, but to win is the key thing because you get a better semi-final.
"I'll have enough rest and enough energy to definitely try [for the world record]. But we will see tomorrow how it goes."
Bolt's major rivals, including Justin Gatlin, made it through safely along with all three British competitors: team captain Adam Gemili clocked 20.20, Nethaneel Mitchell-Blake 20.24, while Danny Talbot equalled his personal best of 20.27.
Becky James won silver and Katy Marchant took bronze in the Olympic women's individual sprint at Rio 2016.
James was beaten 2-0 in the gold-medal final by Germany's Kristina Vogel, while Marchant defeated the Netherlands' Elis Ligtlee 2-0 in the third-place play-off.
James' progression to the final rounded off an excellent week of racing in which she also won silver in the keirin and re-announced herself as one of the best sprinters in the world following two years of injury and illness.
Marchant, meanwhile, claimed her first Olympic medal and in doing so ensured every member of Britain's Olympic track team had visited the podium in Rio.
James said: "I couldn't ask for much more. A year ago I was in a training camp in Valencia and it was my first one back [from injury] and I was so off the pace.
"If I could have seen myself now back then, I would never had expected this. It's a good thing to look back on. I've just felt incredible being here and I'm really, really happy with how I raced."
Both riders breezed into the semi-finals with 2-0 wins in the best-of-three quarter-finals and although James secured another 2-0 to beat Ligtlee in the semis, Marchant fell to a 2-0 defeat to Vogel.
Marchant secured a 2-0 triumph over Ligtlee in the bronze final in a photo finish in the second heat, but James was unable to trouble a dominant Vogel.
Giles Scott won GB's 17th gold in the men's finn sailing on Tuesday as Hannah Mills and Saskia Clark guaranteed another will follow.
Scott needed only to finish the final race of the competition to secure gold and a fifth straight British success in the event following Sir Ben Ainslie's hat-trick of titles and Iain Percy's 2000 win.
And the 29-year-old obliged with a second-placed finish behind United States sailor Caleb Paine.
Paine's victory was good enough to earn him a bronze medal, with silver going to Slovenia's Vasilij Zbogar.
Wednesday's women's 470 medal race will now be a lap of honour for Mills and Clark, meanwhile, after they finished the day with an unassailable lead.
The British pair are 20 points better off than their nearest rivals - New Zealand's Jo Aleh and Olivia Pownie - and are guaranteed to go one better than their silver-medal finish in London four years ago.

Ireland's Annalise Murphy earlier won a silver medal in the women's laser radial event, four years after she finished fourth in London.
Murphy told RTE: "I don't know whether I'm laughing or crying, I was just so happy with how I sailed this week and that last race I just put everything together really well. I'm over the moon."
Amy Tinkler and Nile Wilson took Great Britain's gymnastics medal tally to seven with bronze medals on day eleven at Rio 2016.
Tinkler, the youngest member of the Team GB squad at Rio 2016, took a third place in the women's gymnastics floor exercise and was followed a few moments later by Wilson's bronze on the men's high bar.
Tinkler, 16, took to the floor against the brilliant Simone Biles and while it was the American who took her fourth gold medal of the Games, Tinkler produced a wonderful performance to take third just four years after watching on as a 12-year-old at London 2012.
Biles, already winner of a gold in the team and individual all-round events, added to the vault gold and beam bronze she took a couple of days ago with a sensational routine that saw her awarded a brilliant score of 15.966.
Tinkler produced a superb performance to claim a fantastic bronze medal
But for Tinkler, she went one better than the fourth place GB took in the women's all-round event last weekend with a routine score of 14.933 that saw her become Britain's second female individual gymnastics Olympic medalist.
Another American, Alexandra Raisman, took the silver medal to complete an American 1-2 before Wilson took to the floor in the spectacular high bar.
Going third of the eight contenders, he produced a score of 15.466 after Germany's Fabian Hambuechen had racked up 15.766 with the first performance which was to be good enough to claim gold.
Nile Wilson won GB's seventh medal of the gymnastics competitions with bronze in the high bar
Wilson had the daunting task of following the gold medalist of London 2012 Epke Zonderland, but the Dutchman suffered a nasty fall to ruin his hopes of defending his title.
Wilson, 20, from Leeds, watched on as nobody was able to overtake him until America's Danell Leyva, with the last routine of the final, pipped him to silver with a score of 15.500.
Wilson and Tinkler add to the two golds (floor and pommel horse) and one bronze medal (individual all-round) won by Max Whitlock, a silver for Louis Smith (pommel horse), a bronze in the men's all-round team and a brilliant silver for Bryony Page in trampoline.
Sir Bradley Wiggins became Great Britain's most decorated Olympian at Rio 2016 while Jason Kenny joined Sir Chris Hoy as the country's most successful and Laura Trott also became GB's first ever four-time female gold medallist.
Track cycling again led the way for a brilliant Olympics with Wiggins winning his eighth Olympic medal and fifth gold as part of GB team pursuit four at the 2016 Games, having previously picked up at least one gong at every Games since Sydney in 2000.
His performance moved him ahead of Sir Chris Hoy's tally of seven, although six of the Scot's were gold and Hoy was joined on that number when Kenny added his name to the list with three golds in Rio.
Not to be outdone, Trott became Britain's most successful ever female Olympian...twice. Having claimed a third gold in the team pursuit to become the first to three, she was joined by Charlotte Dujardin on that mark a few days later.
But on the final day in the velodrome she took a dominant win in the omnium to claim her fourth.
Following the achievements, we run the rule of some of the finest names in British Olympic history
Sir Bradley Wiggins - track and road cycling
Wiggins and the GB pursuit team won gold at Rio 2016
Eight medals: 5 golds, 1 silver, 2 bronze
Wiggins eased into his Olympics career with a bronze in the team pursuit in 2000, before heading to Athens and winning gold, silver and bronze respectively in the individual pursuit, team pursuit and Madison events.
Four years later in Beijing he picked up two more golds on the track in the team pursuit and individual pursuit events, before switching to the road at London 2012, where he won the time trial.
Wiggins now has eight after his gold in Rio, and it remains to be seen whether he'll attempt to go on to Tokyo in four years in an attempt to claim any more.
Sir Chris Hoy - track cycling
Sir Chris Hoy
Seven medals: 6 golds, 1 silver
Hoy, in attendance at the Rio velodrome as Wiggins created history, became Great Britain's most successful Olympian in history at London 2012 as his two golds took his tally to six.
The Scottish cyclist won silver in the team sprint at the Sydney Games in 2000, before claiming his first gold in the 1km time trial in Athens four years later.
Hoy then gained a knighthood for his exploits in Beijing as he won three more golds - in the individual sprint, team sprint and keirin, before triumphing again in the latter two events on home turf in 2012.
Jason Kenny - track cycling
Jason Kenny celebrates gold in Rio with victory in the individual sprint
Seven medals: 6 golds, 1 silver
Kenny won gold alongside Hoy at the Beijing Games in the team sprint, before claiming silver in the individual sprint, having been beaten by his GB team-mate in the final.
The Bolton-born rider then claimed gold in the team sprint in London, while also topping the podium in the individual sprint, where he was selected to compete ahead of Hoy.
In Rio he took gold on the opening night of the track cycling with victory in the team sprint alongside Philip Hindes and Callum Skinner, he added a second with victory over team-mate Skinner in the individual pursuit.
And he joined Hoy as the most successful British Olympian when claiming gold in a dramatic keirin on the same night his fiancee Trott won her fourth.
Sir Steve Redgrave - rowing
Steve Redgrave poses with his five gold medals from five different Olympics
Six medals: 5 golds, 1 bronze
Redgrave may have won one less gold than Hoy, but the legendary rower did top the podium at five consecutive Olympics.
He first triumphed in the coxed four in Los Angeles in 1984, before switching to the coxless pair in Seoul 1988, where he also won bronze in the coxed pair.
He then joined up with Matthew Pinsent for Barcelona 1992 and won gold in the coxed pair again, before the duo repeated the feat in Atlanta 1996, Great Britain's only gold medal at that Games.
Despite initially claiming he wouldn't be going to Sydney, Redgrave then found himself back in a boat in 2000, where he won his fifth and final gold in the coxless four alongside Pinsent, James Cracknell and Tim Foster.
Sir Ben Ainslie - sailing
Sir Ben Ainslie won four gold medals
Five medals: 4 golds, 1 silver
Ainslie won silver in 1996 in the Laser class, before going one better four years later to win his first gold in Sydney.
He then piled on the pounds to compete in the finn class at Athens in 2004, an event he dominated again in Beijing and London 2012, becoming the only sailor to medal at five separate Olympics in the process.
Rather than chase Redgrave's record of consecutive golds, Ainslie stepped away from his Olympic career after 2012 in order to focus on the America's Cup.
Sir Matthew Pinsent - rowing

Four medals: 4 golds
Not satisfied with the three gold medals he won in the boat with Redgrave, Sir Matthew Pinsent decided to go on to Athens in 2004 to win gold again.
Him and Cracknell topped the podium again in Greece alongside Steve Williams and Ed Coode, but he decided not to chase a fifth gold medal in Beijing four years later.
Laura Trott - track cycling
Great Britain's Laura Trott on the podium after winning gold in the omnium
Four medals: 4 golds
Trott picked up the first two of her gold medals at London 2012, just a few miles away from where she grew up in Cheshunt, Hertforshire.
With the women's team pursuit and omnium events included at an Olympics for the first time, Trott won both events and set out in Rio to defend both her titles.
Having teamed up with Joanna Rowsell and Dani King in London, she was again joined by Rowsell in Rio 2016 where Katie Archibald and Elinor Barker helped GB to the pursuit gold again.The win meant she became the first British woman to win three Olympic gold medals - she was followed a few days later by Charlotte Dujardin in Equestrian.
