Hague suffered a knockout loss to Adam Braidwood on Friday night in Edmonton, Alberta.

The Edmonton Police Service said Monday that there has been no criminal investigation into Hague's death.

Fighting out of Alberta, Canada, Hague made five appearances in UFC between 2009 and 2011. He enjoyed a successful debut in 2009, submitting Pat Barry via guillotine choke at UFC 98. He went on to lose his next four bouts inside the Octagon, however.

Hague (21-13) suffered eight career knockouts in MMA, including four within the past 22 months. His professional boxing record was 1-3, with two knockout losses.
