UFC 133 continues to go through changes just weeks before the event is scheduled. Vladimir Matyushenko has been forced out of his main card fight with Alexander Gustafsson. Taking Matyushenko’s place against “The Mauler” is “The Hammer” Matt Hamill. The announcement comes after yesterday’s shake up when it was announced that Tito Ortiz vs. Rashad Evans would be the new main event following Phil Davis pulling out of the event with a knee injury.

The UFC broke the news earlier today.

Matyushenko was the third option to step up into the main event against Evans after Ortiz initially turned down the fight and Lyoto Machida and UFC couldn’t come to terms on how much Machida should be compensated for fighting on three weeks notice. Ortiz had second thoughts though, eventually accepting the fight against Evans, leaving Matyushenko back to his original opponent, Gustafsson. Now Gustafsson has a new opponent in the form of Hamill.

The last time Hamill was in the octagon was this past May, dropping a unanimous decision in the UFC 130 main event against current light heavyweight #1 contender Quinton Jackson. Prior to the loss, Hamill had won five straight fights, including a victory over the aforementioned Ortiz.

Gustafsson is coming off back to back submission victories and looks to keep the momentum going, along with scoring the biggest win of his career, against Hamill.

UFC 133 is scheduled for August 6 at the Wells Fargo Center in Philadelphia, Pennsylvania.
