Bruins coach Claude Julien said Krejci will be a game-time decision.
"I'm not really sure yet, but I will go out there and give 100 percent and try to help the team win the game," Krejci said. "I feel pretty good. It was a good morning skate."
Also, injured Bruins defenseman Adam McQuaid (neck) will not play Thursday night, said Julien.
Fellow blueliner Steven Kampfer (knee) is "likely" to return to the lineup and make his season debut tonight, according to Julien.
McQuaid suffered the injury last week in Carolina and has missed the last two games. The team is treating the injury similar to a concussion, but McQuaid was able to skate Sunday, Monday and Tuesday. He did not practice with the team Wednesday and did not participate in today's game-day skate.
Kampfer suffered a sprained MCL on his left knee during a preseason game on Sept. 29.
"It's been a while but I'm excited for it," Kampfer said of his return. "I'm ready to go and I feel good. I just need to go out there and play my game, keep it simple and help this team get two points."
Rookie defenseman Matt Bartkowski was officially assigned to the Providence Bruins of the AHL Thursday morning. He played a total of three games for the Bruins this season and Julien believes the 23-year-old blueliner needs more of an opportunity to hone his skills with more playing time.
"It's just a matter of him playing a little bit more," Julien said. "I thought his training camp was extremely good. He showed signs of being a little bit better. He got stronger and right now he just needs to go there and play and make some quicker decisions with the puck and knowing what to do when he gets it.
"At times we felt he was maybe a little slow reacting and that kind of got him in trouble at times," added Julien. "More playing time will certainly help him in regards to that."
