Seabrook was boarded by ex-Hawk Rene Bourque and went face-first into the glass at 15:25 in the first period. Seabrook lay on the ice for several minutes. He left the ice without much assistance but didn't return. Bourque was ejected and received a five-minute boarding penalty.

Here's a video of the hit:

Seabrook has been the victim of dirty hits many times in his career and has a history of head injuries. But Seabrook, a major part of the Hawks' success, has shown that he recovers quickly from such injuries.

Last postseason, he was hurt when hit in the head by Raffi Torres in Game 3 of the first-round series against the Vancouver Canucks. During the Hawks' Stanley Cup-winning season, Seabrook was knocked unconscious by James Wisniewski during a game against the Anaheim Ducks. He also suffered a concussion in October that season.

By all accounts, Seabrook felt much better after the game. Defense partner Duncan Keith said Seabrook was "doing a lot better." Coach Joel Quenneville talked with Seabrook just before meeting the media.

"He seemed not bad after the game; it was more precautionary," said Quenneville, who is "hopeful" that Seabrook will travel with the Hawks to Pittsburgh for Tuesday's matchup with the Penguins. "We'll find out more [Monday], but he seemed all right."

Because of where the hit occurred on the ice, few Hawks had a good look at it. But Jonathan Toews had a good view.

"It seems to happen every other game around the league," Toews said. "Seeing what I saw being right in front of it, it looked ugly. When a guy has his back turned and you have more speed than him, it comes down to respect. You hit guys when it's a clean situation. Head shots and head injuries aren't going anywhere if we keep making plays like that, and that goes for everybody in the entire league. Hopefully [Seabrook] makes a recovery."
