Serra must be off his medication. During that fight, the ONLY time Serra had an advantage was in the beginning when he head butted Hughes and followed it up with illegal punches to the back of the head. After that brief stint, Hughes owned him and threw him around. He knows he didn't win that fight, he raised Matt's hand after the final round. He knows he couldn't even win by cheating, so why would he want a rematch where he would most likely get destroyed? Maybe he should talk to Frank Tigg about wanting a rematch with Matt Hughes.
Serra just needs to go away.
