Penguins’ Casey DeSmith done for Rangers series after surgery

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.
