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.
I definitely think going back down helped me, I had a lot of confidence down there, I played a lot of minutes and I think that helped me a lot. With the 37 games up here, that gave me experience as well. I know what it takes to play in the NHL and now it's time for me to show that I'm capable of being a full-time NHL player.
