Petry was hurt in the third period of last Sunday’s 2-1 shootout win over the Carolina Hurricanes.
Defenceman Nathan Beaulieu, who was a healthy scratch over the last two games, will draw back into the lineup against the Lightning.
It was seven days after scratching Beaulieu for the first time this season that Canadiens coach Michel Therrien promoted him to his top defensive pairing with P.K. Subban on Dec. 17. The 23-year-old was dropped down to the third pairing in January before playing his way out of the lineup for last weekend’s games.
"For young players, consistency is always a battle," said Therrien Monday. "It goes with maturity."
In 51 games this season, Beaulieu has two goals, 14 assists and a minus-1 rating.
