It has been nearly two years since Chael Sonnen infamously got himself caught in an Anderson Silva triangle choke with less than two minutes remaining in a fight that would have earned him the middleweight title. However, in less than one month, Sonnen will have a chance to redeem himself when he meets Silva in a rematch at UFC 148.
While it has likely haunted him since the second he was forced to tap, Sonnen's submission loss to Silva at UFC 117 was far from the only embarrassing moment in UFC title fight history. With so much on the line in a single fight, mental mistakes are bound to happen to even the world's top fighters.
As anticipation builds for one of the biggest rematches in MMA history, let's take a look back at Sonnen's loss to Silva and the worst title fight gaffes the UFC has ever seen.
