Phil Davis injured, UFC 133 fight against Rashad Evans off

Breaking news for UFC 133 ... and it's bad.

Phil Davis has reportedly suffered a knee injury in training and has pulled out of his fight against Rashad Evans, which was scheduled for Aug. 6, 2011, at the Wells Fargo Arena in Philadelphia, Pennsylvania.

No word yet on a replacement for Davis or if UFC 133 will get a new main event altogether but the new plan for the headliner of the promotion's return to "The City of Brotherly Love" is expected to be announced soon.

MMAFighting.com brought word of the change just a short time ago.

Davis was given a shot at Evans thanks to an injury that forced a cancellation of the originally planned light heavyweight title fight pitting "Suga" vs. Jon Jones.

It represented a major step up in competition for one of the most promising prospects on the UFC roster but alas, it is not to be. The question now becomes -- is there sufficient time to find Evans a new, worthy opponent by Aug. 6?

The highest ranked light heavyweight currently without a fight booking is Lyoto Machida, who blasted Evans back at UFC 98 to win the 205-pound strap. Rematch, anyone?

There is another name out there who is without an opponent -- Tito Ortiz. That would also be a rematch of a fight that went to a draw back at UFC 73. Up for it?
