Capitals defenseman John Erskine could face supplemental discipline from the NHL for hitting Flyers winger Wayne Simmonds in the head Friday night.

With 1 minute 51 seconds remaining in the first period of Washington's 3-2 win over the Flyers, Erskine elbowed Simmonds in the head as both players pursued a loose puck along the left-wing boards in the Philadelphia zone.

No penalty was called on the play. Simmonds had a bloody nose and was able to head to the bench under his own power, but he never returned to the game.

Flyers General Manager Paul Holmgren said after the game that Simmonds has a "head injury" and "probably a little bit of whiplash" but that he would be reevaluated Saturday.

"When I saw it live I didn't think [it was bad]: Two guys colliding going for the puck," Holmgren said. "But then you see the replay. I don't know why his elbow came up, but it looked like it did. And I don't think John's that kind of player, I don't think he's a dirty player."
