The last time we saw Tim Hague in the Octagon was back in 2011, when he lost to Matt Mitrione. But he was a UFC vet nonetheless, and now, after a poorly-sanctioned boxing match in Edmonton, Canada, he’s gone.

Here’s MMAFighting with the sad news.

Tim Hague, a UFC veteran, is dead at age 34, two days after suffering a boxing knockout Friday night.

Hague died Sunday at a hospital in Edmonton after being in critical condition all weekend, his family said in a statement posted to his sister’s Facebook page. Hague was knocked out in the second round by fellow heavyweight Adam Braidwood at an event promoted by KO Boxing Canada.

“It is with incredible sadness, sorrow and heartbreak to report that Tim has passed away today,” the statement read. “He was surrounded by family, listening to his favorite songs. We will miss him with [us] so greatly. We ask for privacy during this difficult time.”

Braidwood, a former football player, knocked Hague down several times during the bout, but the referee didn’t call for a finish until one punch left Hague out cold in the second round. Hague was 1-2 as a boxer going into the fight, while Braidwood was 7-1 with six knockouts.
