Head coach Martin St. Louis said Monday that Slafkovsky's (shoulder) status for Tuesday's game against the Rangers is uncertain, Eric Engels of Sportsnet reports.
Slafkovsky sustained a shoulder injury during Friday's practice session but was able to suit up for Saturday's game against the Islanders. He was effective, tallying two assists in the shootout loss, but it's not yet clear whether he'll be able to dress for Tuesday's home game.
