WILMINGTON, Mass. — After taking Sunday off, the Boston Bruins are practicing at Ristuccia Arena.

One week after surgery to repair a facial fracture, Michael Ryder has rejoined the team for the first time. He’s wearing a full cage and a red “no-contact” jersey, but he’s out there.

Winger Chuck Kobasew, out since suffering an upper-body injury last Tuesday, is out there as well — skating with Patrice Bergeron and P.J. Axelsson like he had been before the injury.

While the Bergeron line is back together, two lines have been juggled for this practice — with Blake Wheeler joining Marc Savard and Milan Lucic, and Phil Kessel joining David Krejci and Vladimir Sobotka.

UPDATE: The Bruins are working on their power play (10:45 a.m.), and the old first unit is back together¬† — with Bergeron at one point opposite Zdeno Chara and Kobasew, Axelsson and Savard up front. The other man-advantage group features Dennis Wideman, Andrew Ference, Krejci, Wheeler and Lucic. The last two games, the Bruins’ power-play units looked different, including Bergeron playing up front.

I’ll have more later.
