STOCKHOLM - Thiago Silva has a lot to prove.
After failing a drug test in early 2011 after altering his urine sample, sitting out a year due to the accompanying suspension, and now getting a slot in a UFC main event, Silva needs to prove to fans and UFC officials he's worthy of his top billing at UFC on FUEL TV 2.
But as he told MMAjunkie.com, more than anything, he needs to prove to himself that he's the fighter he once was.
