UFC legend Stephan Bonnar has died at the aged of 45.
The Hall of Famer passed away on Thursday with reports suggesting he died of heart complications. Bonnar is widely credited with sparking an explosion of interest in mixed martial arts thanks to his rivalry with Forrest Griffin.
The pair met in the final of The Ultimate Fighter in 2005 with the fight widely credited with rescuing what was a struggling promotion. Bonnar lost the light-heavyweight clash but recovered to win his next three fights in the UFC.
