As per the Twitter feed of NESN reporter Naoko Funayama, Bruins center Vladimir Sobotka skated during practice today at Ristuccia Arena. Sobotka, it was revealed, suffered a “slight concussion” against Atlanta Tuesday night. He did not play Thursday against Tampa Bay.

Defenseman Andrew Ference, however, did not practice. He told reporters that he will probably take days off between games to make sure his balky groin holds up for the rest of the season.

The Bruins host Calgary in a matinee Saturday.
