UFC's Jon Fitch out six months with shoulder surgery, hopeful for B.J. Penn rematch

They've sweat and bled together for years, and American Kickboxing Academy teammates Jon Fitch and Cain Velasquez now have another reason to commiserate.

Fitch learned Tuesday that a shoulder injury he sustained in a fight with B.J. Penn requires surgery and is likely to keep him out of action for up to six months.

Fitch told MMAjunkie.com he hoped that physical therapy could get him through the problem before receiving word on Tuesday that he needs to go under the knife.
