Markov was injured during the third period of the game on the Leafs' third goal. The veteran defenceman was scrambling to get back in position when the skate of a sprawling Carey Price cut Markov around the ankle area and sliced a tendon.
Markov underwent surgery overnight in a Toronto hospital to repair the slice tendon, and RDS had confirmed that he will be out for 3-4 months.
This is the second straight game that Markov has been injured at the Air Canada Centre. During Montreal's final regular season game there last season, he was run into the boards from behind by Mikhail Grabovski. Because of the hit, Markov sustained an injury to his knee and was forced to miss the rest of the regular season and the playoffs.
The Canadiens are expected to fill the hole left by Markov's injury when Roman Hamrlik returns on Saturday against the Buffalo Sabres. Hamrlik had missed a lot of the pre-season due to a flu. The Habs are also expected to call up defenceman Yannick Weber from the Hamilton Bulldogs of the AHL.
