Blackhawks goaltender Corey Crawford exited in the first period on Sunday night against the San Jose Sharks after a collision in the crease, and did not return.
Coach Jeremy Colliton confirmed after the game that Crawford has a concussion and is currently in protocol.
"He has a concussion, so he'll be under the protocol and go from there," Colliton said. "Didn't talk to him, but of course we're concerned."
The play happened with 1:30 left in the opening frame when Evander Kane shoved Dylan Strome into the Blackhawks netminder, who appeared to hit the back of his head on the post.

Kane was assessed a goaltender interference penalty and Crawford immediately left the game. He allowed two goals on eight shots before getting replaced by Cam Ward.
Crawford missed 47 games last season because of a concussion, so expect the Blackhawks to take a cautious approach with this situation going forward, given his injury history.
