Amir Khan's career came to a crossroads after defeat to Danny Garcia at the weekend, but how does he measure up against the active British Olympic boxing medallists who've joined the professional ranks?
We take a look at the fortunes of the members this elite club:
Audley Harrison — Heavyweight — Sydney 2000 — Gold
Audley came back from Sydney a hero, and appeared to have a weak heavyweight division at his mercy when he turned professional. He signed a lucrative deal to show his fights on the BBC, but drew criticism for fighting hand-picked, easy opponents.
He lost for the first time against long-time rival Danny Williams for the Commonwealth title in 2005, then went Stateside and lost to Dominick Guinn. He avenged the Williams loss, but defeats against Michael Sprott and former taxi driver Martin Rogan appeared to have killed off his career.
Harrison, now a figure of fun in boxing circles, rebounded by winning Prizefighter and then knocking out Sprott when heavily down on the judges' scorecards to earn an unlikely world title shot against David Haye.
When the chance came, he was blasted out in three rounds, scarcely throwing a shot.
He appeared on the BBC's Strictly Come Dancing in 2011, before plotting a return to the ring at the age of 40. He beat unheralded Ali Adams on his return in May.
Record — 28 wins, 5 defeats
Amir Khan — Lightweight — Athens 2004 — Silver
Perhaps it sounds incongruous after a devastating defeat, but Khan has had the most successful career of recent British Olympic boxers.
Khan turned professional after avenging his loss to Mario Kindelan in the Athens final, then constructed an unbeaten run in the professional ranks which took him towards being a contender for a lightweight title in 2008.
But a bewildering loss to Breidis Prescott in just 54 seconds raised huge questions about Khan's chin and ability at the highest level.
He answered many of those questions after switching trainers to work with the renowned Freddie Roach, stepping up to light welterweight and winning belts in the division. Talk was bubbling of a multi-million pound showdown against Floyd Mayweather Jr in due course, before a controversial defeat at the hands of Lamont Peterson was followed up by a crushing knockout on Saturday when facing WBC champion Danny Garcia.
Record — 26 wins, 3 defeats
James DeGale — Middleweight — Beijing 2008 — Gold
After winning the gold in the middleweight division in China, DeGale was the most high-profile boxer to emerge from the Beijing Games.
He, along with fellow amateurs Frankie Gavin and Billie Joe Saunders, joined Frank Warren's stable in 2009. DeGale began convincingly, with several knock-outs en route to a 10-0 record, picking up the British super-middleweight title along the way.
But he lost a grudge match against long-term rival George Groves in May 2011 to set his prospects back. After a five-month absence, he fought Piotr Wilczewski for the EBU super middleweight title and won, before defending his belt against Cristian Sanavia in his last outing in April.
Record — 12 wins, 1 defeat
Tony Jeffries — Light heavyweight — Beijing 2008 — Bronze
Jeffries turned pro after the Beijing Olympics and turned his attention to the light heavyweight division, fighting mainly in his home town of Sunderland.
He won his first seven fights before a disappointing draw with Michael Banbula, an opponent with a record of 10 wins and 25 losses.
Since that point Jeffries has only fought twice more — both straightforward victories. Now 27, his progress has been hindered by hand injuries. Surgery conducted in 2011 has still not completely resolved the problem, and Jeffries admitted last month that it could end his career if a doctor's plan does come to fruition.
"I've been offered the treatment for free from the same doctor who has given it to so many celebrities and sports stars," he said. "He wants to do the more advanced treatment where rather than taking blood from my arm, they take it from my bone marrow. He will then inject the blood cells into my hands. This really does seem the last resort for my hands and for my career in boxing."
Record — 9 wins, 1 draw, 0 defeats
David Price — Heavyweight — Beijing 2008 — Bronze
Price has made the most impressive start of any of his peers to his professional career.
The Liverpool boxer has knocked out 11 of 13 opponents to date, and claimed the British title with a thumping victory over Sam Sexton.
The fighter's punching power has come to the fore since he left the amateurs, and with his six foot eight inch-frame, the future looks rosy for the 29-year-old.
Where he goes next will be crucial in determining the trajectory of his career, however.
Price has been touted for bouts against the likes of fellow British heavyweights Tyson Fury, Dereck Chisora and even David Haye before he considers stepping up to world level and taking on the Klitschko brothers in years to come.
Record — 13 wins, 0 defeats
