Petry (upper body) isn't expected to play Saturday versus St. Louis, Arpon Basu of The Athletic reports.

EDGE Analysis

Although he's not expected to be available against the Blues, Petry was on the ice for Saturday's morning skate, so he could be ready to return to action sooner rather than later. Kale Clague will likely continue to skate on Montreal's bottom pairing until Petry's cleared to play.
