The UFC announced today that Jon Jones has pulled out of his first title defense against former teammate Rashad Evans and Phil Davis will step in to fight Evans.

Jon Jones explains the details of his injury with Authentic Sport Management:

"(The torn tissue in my right hand in the area between my thumb and forefinger) is an injury that’s been recurring since I was a college wrestler, it doesn’t affect my punching or grappling, but I am taking the time and the proper measures to correct this now, so that it doesn’t happen again. I look forward to getting back to training and to my first title defense. As for Rashad, let’s see what happens with Phil Davis. I will be watching that fight with great interest."

Rashad Evans talks to Authentic Sport Management about the change in opponent:

"I’m looking forward to fighting Phil Davis August 6th at UFC 133, he’s a strong wrestler and a rising star in the light heavyweight division. I wish Jon Jones a speedy recovery, he has something that belongs to me and when he’s ready, I’ll be waiting."
