Petry missed Monday's practice session and will be a game-time call versus Detroit on Tuesday due to an undisclosed injury, John Lu of TSN.ca reports.
EDGE Analysis
While the Habs didn't provide any details regarding the nature of Petry's absence, the fact that he is at least a game-time decision Tuesday should be an indication it's not a serious injury. Still, without Petry, Montreal will have to rely even more on Ben Chariot and Alexander Romanov to log big minutes on the blue line.
