Calgary Flames defenseman Dennis Wideman has been suspended for 20 games by the NHL for his check on linesman Don Henderson.
The league handed down the ban on Wednesday following Wideman's hearing with the NHL's department of hockey operations on Tuesday.
Wideman's suspension will cost him $564,516.13 from his 2015-16 salary, which will go to the players' association's Emergency Assistance Fund.
Wideman committed the offence in the second period of last Wednesday's game with the Nashville Predators, hitting Henderson from behind on his way to the bench after being knocked down himself.
The 32-year-old later explained his actions by saying he was in pain and just trying to get off the ice, adding that he could not avoid Henderson. Wideman said he apologised to Henderson after the incident.
