During the 2008–09 Heineken Cup quarter final against Leinster, Williams faked a blood injury to allow a tactical substituition to reintroduce Nick Evans leading to the bloodgate scandal. This resulted in a 12 month ban for Williams, (reduced to four months on appeal), a three year ban for former director of rugby Dean Richards and a two year ban for physiotherapist Steph Brennan from the ERC as well as a £260,000 fine for the club.
