If anyone, McAvoy understands what Rask might be going through. McAvoy missed 20 games this season with a concussion.
"You don't wish that on their goalie; you don't wish that on anyone," McAvoy said. "[Chytil] goes in a million miles an hour, he hits him. Like I said, it looked like unavoidable contact. Obviously Tuukka took the brunt of that. There's no way for him to prepare. He's doing his job. He's trying to focus on the puck, and the culmination of that play is just unfortunate."
The Bruins were not placing any blame for the injury.
"I don't think there's intent to hit the goalie. I think that's rare," Boston coach Bruce Cassidy said. "There's probably a player or two that tries not to get out of the way, for sure. I don't think this kid tried to hit him. I think he did hit him."
The small benefit for the Bruins is the game marked the start of their five-day break. Paired with the 2019 Honda NHL All-Star Game on Saturday, the Bruins do not play again until Jan. 29, when they host the Winnipeg Jets.
"The timing is probably the best it's ever going to be if you're going to have this injury because you do have [10] days before you play again," Cassidy said. "But there is no good timing. Having said that, who knows how it will play out for him? It's unfortunate."
Rask tied Tiny Thompson for the Bruins all-time record for goalie wins on Thursday against the St. Louis Blues with 252. But for now, the Bruins are just focused on making sure Rask is healthy as he goes through the NHL concussion protocol.
"You're obviously very concerned any time a teammate gets hit like that," forward Brad Marchand said. "He didn't look great coming off. It's nerve-wracking."
