Former UFC champion Mark Coleman has decided to officially call an end to his career. “The Hammer” made the announcement on his Facebook page.

Coleman (16-10) has not competed since a 2010 loss to Randy Couture. The 48-year-old stated he must undergo total hip replacement surgery next week, and will not be able to fight again.

During his legendary career, Coleman netted UFC tournament title honors twice, was the first-ever UFC heavyweight champion, and won the 2000 PRIDE Open Weight Grand Prix. He was also inducted into the UFC Hall of Fame, and owns wins on his resume over the likes of Dan Severn, Mauricio “Shogun” Rua and Don Frye.

How will you fans remember Coleman? As the legendary godfather of ground-and-pound, or as the man who tried to continue fighting in his 40s?
