Sherdog’s Top 10: Longest Major MMA Title Reigns

2. Georges St. Pierre | UFC Welterweight -- 2,064 Days

The popular Canadian has his detractors, but no one can argue with his results. Following a shocking knockout loss to Matt Serra at UFC 69, St. Pierre made the necessary corrections and never again tasted defeat.

“Rush” regained the Ultimate Fighting Championship welterweight crown in his rematch with Serra at UFC 83, punishing him with a series of savage knees to the body on the ground. From there, St. Pierre denied all challengers, besting Jon Fitch, B.J. Penn, Thiago Alves, Dan Hardy, Josh Koscheck, Jake Shields, Carlos Condit and Nick Diaz.

St. Pierre’s last successful title defense came in a split decision over Johny Hendricks at UFC 167 on Nov. 16, 2013. Shortly after, he announced he was vacating the championship to take a break from mixed martial arts. To this day, St. Pierre remains on the sidelines, even as rumors swirl about his possible return.
