Erskine and Simmonds were racing for the puck near the left point in the first period on Friday night when Erskine appeared to lash his elbow out at Simmonds, landing a devastating blow that left the Flyers forward hurting on the ice with a bloody nose. No penalty was called on the play but Simmonds did not return to the game after the hit.
Philadelphia general manager Paul Holmgren stated after the game that Simmonds suffered a head injury and some "whiplash" from the hit and would be reevaluated on Saturday.
Erskine will have a supplemental disciplinary hearing with NHL Vice President of Player Safety Brenden Shanahan at 2 p.m. ET. The veteran defenseman has never been suspended and is not generally known as a "dirty hitter," although there was a borderline hit on Trevor Daley of the Dallas Stars in November of 2011.
