After days of speculation, Calgary Flames defensemen Dennis Wideman has been suspended 20 games without pay by the NHL, for Physical Abuse of an Official under Rule 40.
The suspension stems from a play on January 27 in a game against the Nashville Predators when, after sustaining a hit from Preds forward Miikka Salomaki, Wideman skated to the bench and knocked linesman Don Henderson to the ice from behind. He will, as a result, potentially forfeit US$564,516 (or CAD$775,814) -- the NHLPA has appealed the suspension.
Here's the NHLPA statement on Wideman's behalf, which claims there was "medical evidence" presented at the hearing.
