BOSTON – The Bruins were excited to get back on home ice for the first time this preseason when they suited up against the Philadelphia Flyers on Monday night at TD Garden.

The enthusiasm lasted about 20 minutes as David Krejci left Boston’s preseason home opener after playing two shifts in the first period with a lower-body injury. Krejci finished with 1:55 of ice time in the first period and was missing from the bench at the start of the second period after appearing to tweak his right ankle/knee after a collision in front of the Flyers net with Shayne Gostisbehere.

It was a short-lived Krejci preseason debut for the Bruins just as Zdeno Chara, Brad Marchand, David Pastrnak and Tuukka Rask were all appearing in their first game action during the 2019 exhibition season.

Now the Bruins have to hope that the 33-year-old Krejci is going to be okay with the regular season opener just less than two weeks away, and the Bruins holding little real depth when it comes to top-6 centers. Sure, Charlie Coyle could push up and fill in for a short period of time behind Patrice Bergeron, but the 35-year-old Bergeron is another playing taking it slowly this preseason while coming back from a nagging groin issue.

"I don't think it's serious," Bruce Cassidy said after the game. "We'll know more tomorrow."

Krejci played 81 games last season for the Bruins while posting 20 goals and 73 points, and was in the midst of the Bruins trying to find a right winger to go with No. 46 and Jake DeBrusk on the Bruins second line.
