The following is from the official website of former UFC Welterweight champion, Matt-Hughes.com:
Matt Serra Withdraws from UFC 79 Due to Injury
November 23rd, 2007
As of now, Matt Serra is out of the fight because of a herniated disc in his lower back. I believe Serra is actually hurt, so I don’t think this is just a ploy not to fight. Before my Royce fight, I had three bulged discs that I was able to repair enough to fight. As everybody knows you never go into a fight 100%. So, I’m just going to continue to train until I find out what’s next. -Matt
