Jun 2, 2012 - Another day, another UFC fighter pulls out of an upcoming bout due to an injury.

On Saturday, WrestlingObserver.com reported that a knee injury forced Jon Fitch to withdraw from his UFC on FUEL TV 4 fight against Aaron Simpson. MMAFighting.com later confirmed the story with Fitch's trainer "Crazy" Bob Cook.

No word just yet on who will replace Fitch against Simpson, who is scheduled to make his welterweight debut on the card.

Fitch (23-4-1, 1 NC) was looking to bounce back from the worst loss of his career in December -- a 12-second knockout to Johny Hendricks at UFC 141.

UFC on FUEL TV 4, headlined by Mark Munoz vs. Chris Weidman, will take place Wednesday, July 11, at the HP Pavilion in San Jose, Calif.
