Penguins coach Mike Sullivan said goalie Casey DeSmith will miss the remainder of the postseason after undergoing core muscle surgery Friday morning.
DeSmith departed the Penguins’ triple-overtime victory in Game 1 during the second extra session.
With regular-season starter Tristan Jarry sidelined with a broken foot, Domingue relieved DeSmith and made 17 saves in the series opener before Evgeni Malkin netted the game-winner in triple overtime. The 30-year-old Domingue allowed five goals on 40 shots in the Rangers’ 5-2 victory in Game 2 at the Garden.
Sullivan has said Jarry is day-to-day, but the All-Star netminder didn’t participate in Pittsburgh’s optional practice on Friday. Alex D’Orio was recalled from the AHL to back up Domingue in Game 2.
