Jermain Taylor

Jermain Taylor is an American former professional boxer who competed from 2001 to 2014. He remains the most recent undisputed champion in the middleweight division, having defeated Bernard Hopkins in 2005, and in doing so ending Hopkins' ten-year reign as middleweight champion. This made Taylor the first male boxer in history to claim each title from all four major boxing sanctioning organizations in a single fight. He defeated Hopkins in a rematch six months later, making him the only boxer to have defeated Hopkins twice. Taylor retired as a world champion in the months that followed his capture of the International Boxing Federation (IBF) middleweight title for a second time in 2014, after making a substantial recovery from a brain injury sustained earlier in his career.
