The Toronto Maple Leafs will likely have to face the rest of their playoff push without Colby Armstrong.

During the second period of the Leafs' 6-2 loss to the Tampa Bay Lightning on Monday night, Armstrong broke a foot while blocking a shot by defenceman Mike Lundin, an injury that could sideline him for the rest of the season.

Head coach Ron Wilson made the grim announcement after the game.

"It's been, unfortunately, one of those years for him, breaking things, a mysterious eye ailment, stuff like that," Wilson said. "There's not much we can do now. There are other people who have to fill in for him."

Toronto will miss the hard-nosed, hard-hitting player with a knack for getting under the skin of his opponents.

Armstrong, 28, has only played in 49 games this year, collecting eight goals and 15 assists to go along with 38 penalty minutes. He has been sidelined this season with a finger injury and a scratched cornea, a direct result of a punch by former Atlanta Thrasher Ben Eager. Eager received a four-game suspension for his actions.

He signed a three-year deal worth $9 million US with the Leafs in July 2010 after spending the previous 2½ seasons with the  Thrashers.
