Dennis Wideman, Calgary Flames Defenceman, Suspended For Knocking Down Linesman

Calgary Flames defenceman Dennis Wideman has been suspended for 20 games by the NHL for checking linesman Don Henderson from behind and knocking him down.

During the second period of the Flames' 2-1 loss to Nashville on Jan. 27, Wideman was checked hard into the boards by Predators winger Miikka Salomak.

Wideman banged his stick on the ice en route to the players' benches and then knocked Henderson down in front of the Predators' bench.

Wideman said he was in pain and was just trying to get off the ice, adding that he couldn't avoid Henderson. He apologized to Henderson after the incident. No penalty was called.

The 32-year-old from Kitchener, Ont., was summoned to Toronto for a hearing with the NHL's department of hockey operations Tuesday.

Wideman will forfeit $564,516 in salary.
