BOSTON — The Boston Bruins were missing an important piece of their lineup during overtime Thursday night.

David Krejci left in the third period of Boston’s thrilling 3-2 overtime victory against the Columbus Blue Jackets at TD Garden in Game 1 of the Stanley Cup playoff second-round series after taking a pair of large hits from ex-Bruins Riley Nash. The center did not see a shift in overtime.

After the game, head coach Bruce Cassidy shared what he knew about Krejci.

“I have not talked to him,” Cassidy said. “He didn’t finish the game. I would rule him as day-to-day for now … not (a) concussion. … By the time that he’s available to come back the game’s over. So we’ll see how he is in the morning.”

It’s certainly reassuring it’s not concussion, but Bruins fans likely will be holding their breath until a further update becomes available.

Game 2 at TD Garden is set for Saturday, and Cassidy hopes to have his second-line center in the lineup for puck drop.
