Calgary Flames defenseman Dennis Wideman has been suspended indefinitely pending a hearing for checking and knocking down linesman Don Henderson on Wednesday night.
Wideman will have a hearing Tuesday with the NHL's department of hockey operations.
During the second period of the Flames' game against Nashville, Wideman got up after being hit and struck Henderson on the way to the bench. Wideman said he was in pain and was just trying to get off the ice, adding that he couldn't avoid Henderson.
Wideman apologized to Henderson after the incident.
