Eaves crumpled to the ice Wednesday and eventually made his way back to the locker room. He's had concussion problems in his career and also broke his jaw in November 2011. This injury was announced as an upper-body injury, and Eaves is questionable to return against the Maple Leafs.
Lupul was given a minor penalty on the play. He was suspended two games last season for an illegal hit to the head.
Eaves has played in 10 games this season for the Red Wings.
I remember the first time at Wrigley Field all of us had the long johns, the turtlenecks and the extra equipment because we were afraid of being cold. Halfway through the first period everybody's ripping everything off and we just ended up wearing what we would normally wear for a game at the United Center.
