Former UFC heavyweight Tim Hague, who has been hospitalized in intensive care since being knocked out in a boxing match Friday, was taken off life support Sunday and died at the age of 34. 

The Canadian fighter was knocked out by Adam Braidwood in a match Friday night in Edmonton, Alberta, Canada. Hague's head bounced hard off the canvas as he fell.

Sportsnet reported Saturday that Hague had undergone surgery to relieve pressure around his brain and was in a coma. Other reports stated he was brain dead. 

RealFightStories.com reported Saturday night that Hague was on life support as his family made arrangements for organ donations. Jackie Neil, identified as Hague's sister, told Sportsnet via email that her brother was in critical condition. Neil later wrote in a statement released by the family that her brother had died.

"It is with incredible sadness, sorrow and heartbreak to report that Tim has passed away today," Neil wrote. "He was surrounded by family, listening to his favourite songs. We will miss him with so greatly. We ask for privacy during this difficult time."

Hague had a record of 21-13 as a mixed martial arts fighter, appearing in five UFC bouts between 2009 and 2011.
