Arizona Coyotes captain Shane Doan headed straight to the dressing room during the third period of Saturday's game against the Philadelphia Flyers after being hit into the boards by defenseman Radko Gudas.

While carrying the puck into the Flyers' zone, Gudas knocked Doan down and sandwiched the Coyotes forward's head into the boards, leaving him stunned on the ice.

Doan's immediate reaction was especially worrisome, as it appears he may have suffered a head injury.

Gudas, who was recently suspended three games for an illegal check on Ottawa Senators forward Mika Zibanejad, wasn't penalized on the play.
