The City of Edmonton has chosen a company to review a boxing match involving Tim Hague, who died from injuries two days after the event.

Exactly two months after 34-year-old boxer Tim Hague died in hospital after being injured in a fight at Edmonton's Shaw Conference Centre, his sister says her family is frustrated the city has yet to launch a probe into his death.

The family of former UFC fighter and boxer Tim Hague said he "fought to the very end" and passed away Sunday after two days in critical condition.
