Penguins' Kris Letang: Third period hit causes injury

Letang left Tuesday's game against Montreal with an undisclosed injury after taking a check from behind along the boards.

Analysis:

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 over 18:55 of ice time before leaving the contest.
