Chambers was branded a national disgrace after testing positive for tetrahydrogestrinone in 2003. He was banned for two years, fined and stripped of his medals which resulted in team-mates Darren Campbell, Marlon Devenish and Christian Malcolm also losing their golds for their 2002 World Championship relay success. After dismal spells in American Football, and Rugby League, Chambers made his second comeback last year, attempting to enter the Olympics – for which he received a lifetime ban. Having failed in his bid to run in Beijing, Chambers set his sights on competing at the London Olympics. Best of luck with that Dwain.
