NHL referee Chris Rooney “checked out OK” after this scary incident during last night’s Colorado Avalanche-Dallas Stars game. Thank God.

Stars defenseman Jamie Oleksiak’s slap shot took an unfortunate deflection off a skate and flew right into Rooney’s skull. He lay on the ice motionless for a minute before gathering the strength to skate off.

That’s probably going to leave a hell of a mark, but it could have been a lot worse.
