The Penguins will be without Casey DeSmith for the remainder of the Stanley Cup playoffs.
Mike Sullivan announced after Friday's optional practice at PPG Paints Arena that DeSmith underwent core muscle surgery on Friday morning and would be unavailable to the team for the rest of the postseason.
DeSmith, 30, made his NHL postseason debut in Game 1 and stopped 48 of 51 shots faced before leaving the game in the second overtime period, limping off the ice as Louis Domingue took over the net and went on to finish the game, stopping all 17 shots faced in the win.
