Video: Behind the scenes of Chris Weidman's UFC 162 upset of Anderson Silva

Chris Weidman pulled off one of the most shocking upsets in MMA history on Saturday when he knocked out Anderson Silva at UFC 162.

Although oddsmakers said beforehand that Weidman was the closest challenge to Silva’s middleweight title over the course of his long reign as champion, the way Weidman won – knocking Silva out in the second round – was what came as the biggest surprise.
