Nov 6 (Reuters) - The Chicago Blackhawks fired head coach Jeremy Colliton and assistant coaches Tomas Mitell and Sheldon Brookbank on Saturday, citing the need for "necessary changes" within the National Hockey League (NHL) team.

"As we look to move forward, we know we must earn back the trust of our fans." Last month, an independent report detailed a lack of action by the team"s senior management after they were made aware of allegations by player Kyle Beach that former video coach Brad Aldrich sexually assaulted him in 2010. read more Derek King, the head coach of the Rockford IceHogs, was named interim head coach. "Our on-ice goal remains the same: to build an elite system of hockey - and we have not delivered on that," Interim General Manager Kyle Davidson said in a written statement.
