Penguins' Kris Letang: Third period hit causes injury
Letang left Tuesday's game with an undisclosed injury after taking a check from behind along the boards.
Coach Mike Sullivan gave no update on the blueliner's status after the game. Losing Letang for any period of time would be a serious blow to the Pens, who rely on him in every facet of the game. He registered three shots and played nearly 19 minutes (18:55) before leaving the contest.
