WILMINGTON, Mass. - David Krejci practiced with the team on Monday at Ristuccia Arena for the first time since being out of the lineup with an undisclosed, day-to-day injury.
The center has missed the past four games, last suiting up on November 6 against the Edmonton Oilers.
He began skating on Friday with Strength and Conditioning Coach John Whitesides before practice.
"I haven't gotten anything from our medial staff yet that says he's cleared to go," Head Coach Claude Julien said following Monday's practice, when asked by a reporter if Krejci would be ready for Tuesday night's game against St. Louis. "So I can't answer that right now."
Krejci practiced in his usual spot, centering Milan Lucic and Seth Griffith.
"He's been coming along and I think he's felt pretty good, from what I'm told," Julien said. "But they want to make sure that they make the right decision, so they haven't cleared him yet for me."
Krejci had missed two games prior to the game against Edmonton, dealing with the same day-to-day situation.
"Well, he was 100 percent last time and somehow by the end of the game [against Edmonton], he didn't feel good again," Julien said. "So we have to take that into consideration as well."
While Krejci skated with the team, Brad Marchand was absent from practice.
Marchand's last shift in Saturday's game against Carolina at TD Garden ended with 13:45 left in the third period. Julien said postgame that Marchand wasn't "injured per se, but he wasn't 100 percent, and it was a safe route to take."
On Monday, Julien labeled the winger "probable" for Tuesday's game.
"It was something that happened and we just wanted to be cautious," Julien said. "And obviously it was a good reason because he wasn't any better [on Sunday] and [on Monday] he was better, so that's why we say probable for [Tuesday]."
"Probable is no guarantee, by the way, right?"
With Marchand absent from practice, Matt Fraser practiced on the left wing with Patrice Bergeron and Reilly Smith.
Chris Kelly, Carl Soderberg and Loui Eriksson skated as a trio, with Daniel Paille, Gregory Campbell and Simon Gagne rounding out the practice lines.
Aside from Krejci's and Marchand's statuses, defensemen Kevan Miller has now graduated to being a game-time decision for Tuesday against the Blues at TD Garden.
"We'll take it one step at a time," Julien said.
"He's been cleared by the medical staff. Now it's up to us, so whether we feel he's had enough practice or feel comfortable putting him in, we'll see about that."
It's been about a month of recovery for Miller, who dislocated his shoulder on October 18 in Buffalo.
"It's tough to watch, obviously, for any guy," Miller said following Monday's skate, speaking with reporters for the first time since the injury. "There's a number of guys in this room all going through the same thing with different injuries and we're still going through some. It makes you want to get back in the lineup, it makes you heal faster."
Miller plays a tough game. After building back his strength, and getting in a couple of practices taking contact, the defenseman feels he's getting back to where he needs to be.
"That's something we kind of focused on, to get back to where I was strength-wise and kind of make sure I can do my job," said Miller.
"You build the strength back up and that's how it is with any injury, knee, back, anything, shoulders have that problem and it's something we've been doing to make it less likely [to get injured again]."
"With anything, when something's not 100 percent, you want to be careful about that," Miller added. "I mean, once you get out there, everything kind of goes away. Like I said before, with any injury, it's always in the back of your mind, but you do the rehab, and you do the strength things in order to make that go away and feel comfortable with it."
After missing 12 games and having played in just six games this season, Miller is hoping he can test that out soon.
"I feel pretty good. It's just up to the coaches at this point now, depending what they see out of me," he said. "But I feel good on the ice."
