Laine, who was also NHL’s rookie points leader entering the day, was escorted to the dressing room after taking the hit from McCabe 13 seconds after the Sabres tied the game 3-3 in the third period.
The Sabres overcame a two-goal decifit and won the game 4-3.
Laine was looking down at the puck when McCabe hit him with his left shoulder. McCabe was not penalized for the hit. Laine appeared to hit the back of his head on the ice as he fell and was down for several minutes before being helped to his feet.
Winnipeg center Mark Scheifele immediately went after McCabe, leading to a brawl involving all of the skaters on the ice except Laine. Scheifele was penalized for roughing.
After the final horn, Sabres goalie Robin Lehner got involved in a 6-on-6 fight in front of the Buffalo net.
Jets coach Paul Maurice had no update on Laine’s condition after the game.
“I don’t have a problem with the hit,” Maurice said. “They hit heads. It was a straight-on hit.”
Laine left KeyBank Center under his own power and was seen boarding the team bus afterwards.
McCabe had a small cut under his eye after the game that he said came from the hit.
Sabres winger Brian Gionta, who scored Buffalo’s third goal of the game, said the series of scrums fired up the team.
“It’s a spark for us, but it also gets their team off their game,” Gionta said. “They are running around trying to avenge the hit, obviously, to a big player on their team. That’s where a lot of the momentum comes from.”
