Breaking News: Hughes Vs. Serra Off, New Match Revealed

Matt Serra was injured Monday training with Matt Arroyo and his back went out. It was serious to the point he had to practically be carried to the hospital. And after an MRI, he had to practically be carried off the table. He didn't tell anyone about it, hoping it would heal. He went to the chiropractor to see if he could make it better, and ended up hurting even worse. The doctors told him there was no way he could fight on Dec. 29, so he canceled yesterday.

Matt Hughes will now face Georges St. Pierre in a five-round main event for the interim welterweight title. When Matt Serra recovers from his herniated disc, a match will be put together to unify the championship.
