Seabrook was hit face-first into the boards by Calgary Flames forward Rene Bourque in Sunday's 4-2 win by the Blackhawks. Seabrook lay on the ice for a moment before being helped off, and he did not return to the game. Bourque was given a major penalty and game misconduct.
On Monday, the NHL suspended Bourque two games for the hit.
The Blackhawks did not practice Monday, so Seabrook's first chance to skate with his team would be Tuesday morning. It's unclear if he will play in the game.
After Sunday's game, coach Joel Quenneville indicated Seabrook was "doing much better" and was held out for precautionary measures. Seabrook has suffered several head blows the past couple of seasons.
Carcillo will miss his third straight game after suffering an upper-body injury Wednesday in Minnesota. He fought in that game against the Wild and also took an elbow to the chin during a scrum around the net.
Penguins star Sidney Crosby is on IR due to concussion-like symptoms after returning from a long layoff for the same problem. Coach Dan Bylsma said Monday "there is no update on Crosby," making his appearance in Tuesday's game unlikely though he is eligible to come off IR at any time.
