Philadelphia Flyers forward Brayden Schenn caught Washington Capitals winger T.J. Oshie with a hit to the head late in the second period of Game 6 on Sunday.
The Capitals forward left for the dressing room and missed the rest of the period, but returned for the third.
Oshie challenged Schenn to a fight off the opening faceoff in Game 5 on Friday night, in response to the Flyers center's cross-check on Washington forward Evgeny Kuznetsov in Game 4.
