According to sources, UFC Light Heavyweight contender, Phil Davis has suffered a left knee injury. Due to the injury, he will have to withdraw from his UFC 133 Co-Main Event match with former champion, Rashad Evans. Davis and Evans were scheduled to meet at UFC 133 on August 6th, but now the UFC is scrambling to find a replacement.

MMA Fighting writer, Mike Chiappetta reports Tito Ortiz was offered Davis’ spot by Dana White but was turned down. Dana White confirmed this in a text to MMA Fighting. This would have been a rematch of the controversial Evans vs. Ortiz match in 2007, which gave Evans the win.

Speculation is that Ortiz (winner of his first fight in 5 years) turned down the spot due to insufficient time to prepare for the fight. The current name floating around as a replacement is Lyoto “The Dragon” Machida but nothing is confirmed at this point.

As of now, Rashad Evans remains oponentless. Should Evans remain on the UFC 133 card, whomever the opponent may be will also potentially suffer from a lack of preparation time.

UPDATE: According to Dana White and Tito Ortiz’ Twitter Account, Tito Ortiz will in fact replace Phil Davis.
