As reported by FiveOuncesOfPain.com and MMAWeekly.com, Frank Mir has suffered an injury that will lead to the cancellation of the rematch to unify the UFC Heavyweight Championship against Brock Lesnar at UFC 98 on May 23, 2009.

According to FiveOuncesOfPain.com, "Multiple sources have confirmed that the UFC was recently informed by Mir's camp that he was forced to withdraw due to injury."

FiveOuncesOfPain.com originally reported it as a back injury, while they corrected themselves as MMAWeekly.com reported it as a knee injury. MMAWeekly.com report called FiveOuncesOfPain.com out and had this to say, "Multiple MMAWeekly.com sources, however, indicated that it is a knee injury that has precluded Mir from training."

Apparently, Mir had knee surgery and will be sidelined for four to six weeks. UFC did not comment on the issue as of yet. This leaves many fans wondering what UFC will do to address this problem.

There are several options they can entertain. Putting the title on the line in a match not featuring Mir seems unlikely. The more likely option is for the UFC to scrap the match for UFC 98 and postpone it until Mir is able to train once again.

UFC 98, set for Las Vegas, may now alter plans for other events since it is now without a main event. The long-awaited Matt Hughes vs. Matt Serra matchup, Yushin Okami vs. Dan Miller, and Sean Sherk vs. Frankie Edgar are all on the card according to UFC.com.

The UFC has set up cards without a championship main event and this particular card could work without one, but UFC needs to fill the MGM Grand Arena and tickets will be going on sale to the public tomorrow. What will the UFC do?
