Don Henderson was sent to hospital for precautionary reasons after a collision with Calgary Flames defenseman Dennis Wideman on Wednesday and has since been released, TSN's Darren Dreger reported Thursday.
The 47-year-old was knocked to the ice after Wideman, who was visibly dazed after being hit into the boards moments before, ran the linesman over from behind.

Sportsnet's Eric Francis reported that Henderson, who was able to finish the game, was in hospital until 5:00 a.m. dealing with "neck pain and nausea," and went through the concussion protocol.
Dreger added that a decision on whether Wideman will be suspended as a result of the collision is expected later Thursday.
