In the wake of Stephen Lee's 12-year ban for match-fixing, the Sky Sports team take a look at some of the high profile falls from grace in the world of sport.
The former world No 5 was banned and charged £38,000, leaving him unable to take to the baize again before 12th October 2024, his 50th birthday.
Lee's fellow snooker star was banned from the sport for eight years in 2006 for agreeing to lose a match at the China Open in a sting by Sun journalists.
The Australian resigned from the World Professional Billiards and Snooker Association (WPBSA) days before his hearing, which he did not attend, and is now a professional pool player.
The Texan was stripped of his seven Tour de France titles and banned from cycling for life in 2012 as the United States Anti-Doping Agency concluded he had been at the heart of "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
The International Cycling Union accepted the findings and the disgraced cyclist himself, after denying doping for so long, finally admitted it in January 2013 in an interview with Oprah Winfrey.
The 2004 Olympic 100 metres champion served a four-year ban from 2006 to 2010 after failing the second drug test of his career.
He initially agreed to an eight-year suspension, but on December 31, 2007 it was reduced to four years. His return to athletics has been successful, winning Olympic bronze at London 2012 and World Championship silver this summer.
The former Pakistan cricket captain was jailed and handed a 10-year ban, of which five years were suspended, in February 2011 after being found guilty of spot-fixing.
He instructed team-mates Mohammad Amir and Mohammad Asif to bowl no-balls to order in a Test against England at Lord's in 2010.
The former British and Irish Lion was banned from coaching for three years for orchestrating the fake blood scandal in 2009 when he was director of rugby at Harlequins.
He returned to the game last year at Newcastle.
The Serbian former world number 12 was banned for 18 months in July for failing to provide a blood sample when requested during in-competition testing at the Monte Carlo Masters in April.
He has appealed the punishment.
