Coyotes center Derek Stepan was the recipient of a hit to the head from Stars defenseman Jamie Oleksiak and was removed from the game with an upper-body injury, per the Coyotes.

The Coyotes did not have an update on Stepan's condition after the game, other than to say he had entered concussion protocol. Stepan appeared fairly agitated when he left the arena Sunday night.
