Blues defenseman Alex Pietrangelo left the ice with 7:20 to go in the third after being hit hard into the boards by Charlie Coyle and appearing to hurt his right knee. He was down on the ice for a while before limping down the hallway to the dressing room. Associate head coach Brad Shaw, filling in for coach Ken Hitchcock in the interview room, said after the game that Pietrangelo was “a little sore. We’ll see how he feels (Sunday).”

from Michael Russo of Russo's Rants,

Charlie Coyle clanked knees with solid Blues defenseman Alex Pietrangelo in the third period and he was hurt. He left the game in discomfort and limped down the runway. I’m told he has an MRI in the morning, so that won’t be good for the Blues if that’s serious. But this is a team that has overcome injury adversity all season long and has found a way to get points.

The Department of Player Safety, like all incidents like this, will review the play to see if Coyle warrants discipline. As you know, he’s far from a dirty player, and although I saw the replay quickly because I was frantically writing, it did look like Pietrangelo tried to jump out of the way. That sometimes affects the way the league looks at these things.
