Carl Froch is one of Britain's most decorated boxers, having won English, British and Commonwealth titles early in his career.
He made a successful move up to elite level, becoming a three-time world champion.
Here we take a look at some of the best fights that helped Froch on his way to greatness.
Charles Adamu - 2004
Froch was already attracting a following in his home town of Nottingham when he beat Charles Adamu on points for the Commonwealth title.
The 26-year-old had earned an 11-0 record with nine wins via stoppage in his fledgling career and was expected to extend his winning streak against the tough Ghanaian.
Adamu had lost his own unbeaten record in Germany just a fortnight earlier but gave Froch his first serious test, taking him the full 12 rounds.
The 'Cobra' had his man down in the eighth round but it was difficult night for the champion before referee Marcus McDonnell gave him the verdict 116-113.
Ruben Groenewald - 2005
The Cobra stops the tough South African for the first time in his career, much to the frustration of the challenger.
Groenewald was well known to British fight fans following two wars with Anthony Farnell but had only fought twice in the intervening three years.
Stepping up in weight against a big puncher like Froch was never going to be a winning formula though.
And while the challenger did his best to duck and weave his way out of trouble, he took plenty of punishment in the early rounds.
And when Froch cornered his man in the fifth, unleashing a flurry of heavy bombs, the referee stepped in to spare Groenewald further punishment.
And while the stoppage appeared a little premature, there was little doubt it that it didn't change the outcome.
Tony Dodson - 2006
Froch moves to 20-0 with another display of devastating power - this time a left hook to the body finishing the challenger.
The Cobra was coming off a stellar win over Brian Magee while Dodson had been relatively inactive - however the Liverpool brawler had been talkig tough in the lead-up to the fight.
The actual contest proved once again, however, that Froch was ready for a step in class despite his somewhat crude style.
The the right hook would become his feature punch, Froch could hardly miss with the left as Dodson was outclassed from the get-go.
A right upper cut hurt the challenger in the third round and a right-left to the body combination put him down - when he tried to get up Dodson crumpled again from the effects of the body shot.
Jean Pascal - 2008
Froch finally gets his title shot and beats the Canadian in an all-out war to claim the WBC strap.
After being ranked in the top three by the WBC for more than two years Froch finally gets his chance to fight for the newly-vacated title.
Destined never to take on the man he has been calling out, Joe Calzaghe, the Cobra takes his career down a different path, proving a granite chin in the process.
Seemingly unconcerned by the big bombs Pascal lands with too much ease for comfort, Froch simply walks through his man to earn victory on all three scorecards, to the delight of a partizan crowd in Nottingham.
Jermain Taylor - 2009
In his first defence, Froch went to Connecticut and stopped Jermain Taylor in the final round when he was behind on two scorecards.
Still finding his feet at the highest level, Froch was floored for the first time in his career by a right over the top in round three.
But he gradually fought his way back, pressurizing the former middleweight champion who was doing little to dispel the belief he lacked stamina.
Froch knew he needed a big 12th round -let alone a knockout - but he hurt his opponent early on with a right hook and from then it was a question of whether Taylor could hang on.
With less than a minute to go, Froch couldn't miss and huge right hand put Taylor on the floor in the corner, and although he beat the count Froch waded in again and with the American defenceless the referee stepped in with 14 seconds left.
Andre Dirrell - 2009
The start of the Super Six saw an awful clash of styles with southpaw Dirrell losing his unbeaten record on a split decision.
The American showed excellent hand speed but his negativity and decision to consistently smother Froch's work did not curry favour with the Nottingham faithful.
Both fighters had success but the turning point came in the 10th round when Dirrell was docked a point for holding on, and although the scores were close Froch deserved to keep hold of his title.
Mikkel Kessler - 2010
Back to his thrilling best, Froch went toe-to-toe with the tough Dane for the full 12 rounds, but tasted defeat for the first time on points.
Kessler had been slowly picked apart by Joe Calzaghe and was going into the fight on the back of a Super Six defeat to Andre Ward.
But there was little sign of deterioration here as the challenger traded from the outset with neither fighter giving an inch.
Following a good natured build-up the friendly foes slugged it out as though there was genuine enmity in the ring, and although Froch felt he had done enough it was Kessler who took the decision - and the WBC belt - on home soil.
Arthur Abraham - 2010
Froch gave himself an easy night by sticking to his boxing skills, winning by a wide margin and regaining the WBC belt vacated by Kessler.
Perhaps worried by Abraham's fire power, the Briton opted to stay out of range after his four previous slugfests.
The tactics appeared to bemuse the German-based Armenian, who did not have a plan B and was out-fought, and out-thought.
The scorecards suggested a virtual shutout - and with Kessler having to give up the title owing to an eye injury, the strap was back around Froch's waist sooner than he thought.
Glen Johnson - 2011
Through to the Super Six final whatever the outcome, Froch does enough on two scorecards to beat the veteran despite taking some big shots along the way.
Johnson had been operating at light-heavyweight for years but answered the SOS from Super Six organisers after other contenders fell by the wayside for numerous reasons.
The bout may have meant little in terms of the competition, but Froch's world title was still on the line and the 42-year-old had to be taken seriously.
The Briton once again had his chin questioned by Johnson's big bombs, and while he took too many for some people's liking the result was never truthfully in doubt.
The only disappointment was that Froch couldn't put his man away, although many have tried and failed in that regard down the years.
Lucian Bute - 2012
Following defeat to Andre Ward in the final of the Super Six the doubters were questioning whether Froch had anything left to give at the highest level.
Bute, the only top super-middleweight not to buy in to the Super Six, had held the IBF strap since 2007 and built-up a 30-0 record.
Such was his pedigree and aura that the Romania-born Canadian came into the fight a strong favourite despite it taking place in Froch's backyard. But how the bookies got this one wrong.
Fighting with an intensity that has become his trademark, Froch overpowered Bute early on and the writing was soon on the wall for southpaw.
The third and fourth rounds were dreadful for the out-going champion and the Briton got the job done in chilling fashion in the next with Bute helpless on the ropes.
