Though a return to the UFC doesn't appear to be in Brock Lesnar's immediate future, the former heavyweight champion isn't ruling it out.
Lesnar made his UFC debut in 2008 after a successful stint in the world of professional wrestling. He went on to claim the UFC heavyweight championship when he knocked out Randy Couture at UFC 91. After he defended his title over Frank Mir at UFC 100, Lesnar was sidelined with a case of diverticulitis. He returned and defended his belt one more time against Shane Carwin before losing it to Cain Velasquez.
