The Harlequins player was given a year's ban from professional rugby after feigning a blood injury to ensure his team could bring on a replacement during Heineken Cup 2009 semi-final against Leinster.

Proving there's no room for cheats in sport, not only was he was also given a £215,000 fine, but the Harlequins didn't win. Funnily enough his replacement for his 'bloody injury', Nick Evens, missed a late drop goal that would have won the match.

Williams used a blood capsule (the type you buy from a joke shop) to attempt to fool officials that his injury was severe. So who's laughing now?
