Boychuk/By S. Bradley

BOSTON — Bruins center David Krejci skated before the team and defenseman Johnny Boychuk joined the full host of his teammates this morning at TD Garden.

Krejci, who hadn’t done any activity until riding the bike Friday, skated for the first time since suffering a concussion last Saturday against St. Louis. He was joined on the ice by winger Marco Sturm, who’s still at least a few weeks from his return from knee surgery, and strength and conditioning coach John Whitesides.

Boychuk, out since Oct. 23 with a fractured hand, skated with the players who were preparing for their game tonight with Ottawa. He is still wearing a cast, which he thinks will be removed this week.

After the morning skate, Bruins head coach Claude Julien offered an update on both players:

“I think both are progressing well. David started his exertion tests yesterday as we mentioned. He got on a bike and felt good enough today, so that he moved on to getting on the ice and skating a little bit today. I guess that result we’ll get later on as the day progresses and how he feels and whether he feels good tomorrow. So those are the things that he’s going through. So, so far everything is going in the right direction for him.

“Johnny it’s the same thing. He started skating with the team today and got some shots. He’s capable of shooting now a little bit and everything else. So he’s progressing well and I guess these next few days will determine how close he is to starting to play again.”

Next Saturday will be four weeks out for Boychuk, which was the original prognosis.
