According to reports, Bellator is interested in signing CM Punk, if he wanted to try changing careers. It has been a well known fact that Punk is a big fan of MMA, where he is frequently seen at UFC events. As many already know, he recently walked out on WWE after some disagreements.
Chris Benoit shocked the wrestling world when he was able to win the Royal Rumble and earned himself a shot at the World Heavyweight Championship at Wrestlemania. He was successfully able to eliminate the Big Show to win the match.
Prior to becoming a star in professional wrestling, Ahmed Johnson, whose real name is Anthony Norris, played middle linebacker for the Dallas Cowboys for two seasons (1990 and 1991). He wasn't a big star, nor did he receive a lot of playing time, so he's not remembered by too many NFL fans.
