WILMINGTON, Mass. — Dennis Wideman, who had been out since suffering a shoulder injury Oct. 10 against the New York Islanders, returned to practice today for the Boston Bruins at Ristuccia Arena.

Also on the ice were new call-ups Vladimir Sobotka and Brad Marchand for the Bruins’ first practice in the post-Chuck Kobasew era.

Wideman’s return means seven available defensemen for the Bruins. Both Tuukka Rask and Tim Thomas were on the ice. Guillaume Lefebvre, Marc Savard and Shawn Thornton are not on the ice and there was no news immediately available as the team practiced.

In a possible psychological move, the Bruins started practice with one line — Marchand, Patrice Bergeron and Michael Ryder — dressed in gold sweaters and the remaining skaters were in grey. But that might just have been because they were shorthanded. About midway through, Sobotka, David Krejci and Blake Wheeler pulled on some brick sweaters, leaving just Mark Recchi, Byron Bitz, Marco Sturm and Steve Begin in those grey threads.

UPDATE: Savard and Thornton were given maintenance days, while Lefebvre was given the day off after he traveled cross country and played in three games.
