Montreal Canadiens defenceman Andrei Markov suffered a torn ACL and will be out indefinitely, Sportsnet can confirm.
Markov was injured in Game 1 of the series against Pittsburgh after a check from Penguins forward Matt Cooke. The team sent Markov home for evaluation and was listed as day-to-day.
Markov missed 35 games with a lacerated tendon in his foot at the start of the year. In eight playoff games this spring Markov has four assists.
