Il se serait déchiré le biceps en faisant un bras de fer avec un rugbyman...
"I had torn my bicep and I just had bicep surgery. I lost my whole tendon. The operation didn’t work, so I was actually worried about just being able to tie my shoes. It’s one of the reasons I wore a gauntlet up here
(motioning to the top of his right arm). I had a big scar. I’m going to have a cadaver tendon put in to fix it. I was arm-wrestling some rugby players at four in the morning. We had been drinking at a pub in London and I lost, but we became good friends."
