Relive The Biggest Upset In MMA History

Back at UFC 69, on April 7, 2007, the biggest upset in MMA history took place. Welterweight Matt Serra won ‘The Comeback’ season of The Ultimate Fighter, a season that featured veterans fighting for a second chance.

Serra won the show and thus earned a title shot against the current champ, Georges St-Pierre.

Obviously Serra was the massive underdog. He was older and smaller and GSP was on the rise and had already taken out some of the best in the sport.

Then the fight took place and Serra pulled off the improbable. He rocked GSP and hurt him. The champ staggered and Serra followed up with more big punches. Pierre went down and Serra stood over him reigning down big shots until GSP rolled over and the referee stepped in and stopped the fight.

What do you guys think, is it the biggest upset ever?
