What It Means:

Letang hurt his knee in the first period of Saturday's game, and being placed on the injured reserve will keep him out of action for at least a week.

Despite his injury troubles, Letang is putting together a solid season. He has 23 points in 30 games played, and his 1.9% Relative Corsi For % at Even Strength is the second-best mark among Penguins defensemen with at least 10 games played this season.
