The incident took place at 12:47 of the first period of The Blue Jackets' 4-3 win over the Red Wings in Columbus on Tuesday. Comeau hit Smith into the boards as the defenceman skated into the Detroit zone to retrieve a loose puck in the corner.
Comeau was assessed a minor penalty for boarding on the play.
Comeau will forfeit US$10,256.42 in salary. He is eligible to return when Columbus hosts Carolina on Tuesday.
