It's his choice. Honestly, I think it proves that he has the will to do well in the industry. If he is willing to risk his health for the chance at a launching pad for a career in music (although I think he'd have no problem with a record win or lose), then he probably has the drive to put in the effort necessary for the business. I've liked him from the beginning, and AI did change the show around once for him, they swapped the girls and boys performance days. He either sucks it up or forfeits. With the recovery time of surgery there is NO WAY FOX will delay the results for 6 weeks. They've got lord knows how many millions of dollars of revenue attached to that time slot for commercials and sponsors.
