Montreal Canadiens defenceman Andrei Markov, who left Game 1 of the Eastern Conference semifinal after being hit by Pittsburgh Penguins forward Matt Cooke, has been diagnosed with a torn anterior cruciate ligament.
Markov, who is out of the Habs' lineup indefinitely, has not officially been ruled out of the series or playoffs by the Canadiens.
The 31-year-old has had a rough season for injuries, as he suffered a lacerated tendon in his left ankle during the Canadiens' first game of the season in October, that caused him to miss 35 games.
Markov had four assists in the Canadiens' seven-game first-round triumph over Washington.
