"I really wanted to fight on the UFC 62 card as planned. I told Joe Silva I'll fight 155 or 170 for a title or a non title fight but they were unable to find an opponent. It looks like I'll be fighting in October now, I just took 2 weeks off training and I'm ready to get back after it now.
I have one goal in mind, to kick the shit out of Florian!!"
