Matt Serra had his Octagon debut way back in 2001 and yesterday the former champ officially called it quits. Serra will always hold one of the biggest upset victories in UFC history when he won The Ultimate Fighter: The Comeback season and was granted an immediate title shot against then, and current champ, GSP. Serra shocked the world and knocked out Georges in the first round at UFC 69. Matt owns a string of jiu jitsu schools in New York and has been more focused on training fighters like Chris Weidman, as well as running his schools. Serra last stepped into the Octagon in 2010 when he fought Chris Lytle and until recently still dreamed of making one last walk to the cage under the UFC banner. “I really think I’m walking away. I’m going to be 39, I just had my rib taken out. I’m having my third kid. My schools are doing well. What am I doing, looking for another pay day? It’s not really for that. I mean, it doesn’t stink, but it’s not really for that. Am I still trying to hold on for the glory? Glory is a drug, dude. I’m telling you, that’s the problem. It really is. I know why guys can’t walk away. I absolutely get it.” The rib Serra is referring to is one doctors removed in April after two blood clots in his arm and one more in his lungs nearly cost him his life. Luckily for Serra he went to the hospital after not feeling well and was able to avoid a tragic ending. It was great watching Serra compete when he did and I am sure he will still be very involved in both the BJJ and MMA worlds. We wish him nothing but happiness in his retirement. Thanks to MMA Fighting for the scope.
