For the second time in less than a month, Calgary Flames forward Matthew Tkachuk was handed a suspension by the NHL Department of Player Safety.

Tkachuk was assessed a one-game ban Thursday for unsportsmanlike conduct against Toronto Maple Leafs forward Matt Martin during Wednesday's game. Amid a scrum, Tkachuk speared Martin from the Flames' bench.

This latest infraction comes after he was handed a one-game suspension last month when, during a game against the Detroit Red Wings, Tkachuk tapped Luke Witkowski on the leg after his opponent had left the ice.

The suspension means Tkachuk will miss Thursday's game against the Montreal Canadiens.
