Senators' Mark Stone: Knocked out of game Sunday

Stone left Sunday's game against the Jets after taking a hard hit to the head from Jacob Trouba, Bruce Garrioch of Postmedia reports.

Analysis:

Stone was down on the ice for a long time before finally heading to the dressing room. Trouba lowered his shoulder into Stone's head and received just a two-minute minor, but there's a good chance he'll be hearing from the league and could face a suspension for the hit. Stone has already suffered a concussion this season.
