Just one week after an injury forced Jon Fitch out of a rematch with BJ Penn at UFC 132, the former champion Penn has also been knocked off the July 2 card.
While the UFC had been searching for a replacement, Penn has been forced out due to an undisclosed injury, according to MMAFighting.
Penn and Fitch fought to a draw earlier this year at UFC 127 and originally agreed to a rematch at UFC 132 with a possible welterweight title shot on the line.
Whether Penn-Fitch II will rescheduled at a later date is unknown at this time.
UFC 132 takes place July 2 in Las Vegas and will be headlined by a featherweight title bout between champion Dominick Cruz and Urijah Faber.
