The England prop admitted in 2009 that he was struggling with a “very serious substance”, understood to be cocaine. He said that he had “an illness” having tested positive after a Heineken Cup game for his club against Glasgow in December and was subsequently handed a two-year ban.
The South African-born prop bounced back admirably from this ban, moving to Saracens and resurrecting his career, and would play at the 2011 World Cup and on the 2013 British & Irish Lions tour.
