Bruins coach Claude Julien classified center David Krejci as day-to-day Monday after the Bruins practiced at TD Garden and Krejci was the forward on the roster missing.

Krejci was a late scratch before the game Saturday night. The Bruins were off on Sunday.

Julien remained mum on whether Krejci’s injury right now is related to the one that forced him to miss the first three games of the regular season.

Also, defenseman Kevan Miller started to skate on his own after the Bruins practiced. Miller has been out with a separated shoulder since Oct. 18. There’s still no timetable for Miller’s return.

The Bruins are back in action Tuesday at home against the Florida Panthers.
