Adam McQuaid made his return from a lower body injury Wednesday night in Detroit, and it looks as if Dennis Seidenberg might just be doing the very same thing on Friday afternoon. The German defenseman was a full participant at the Bruins’ hour-long Thanksgiving morning practice at TD Garden, and Claude Julien termed him a “possibility” for the Thanksgiving Showdown Friday between Original Six foes the Bruins and the New York Rangers. “He’s a possibility,” said Julien. “He felt pretty good today. I haven’t sat down with my trainers to get the lowdown, but I’d have to say he’s a possibility.” The Bruins could certainly use the rock-steady Seidenberg back in the lineup, coming off their worst defensive performance of the season in a 6-1 loss in Detroit on Wednesday night. If Seidenberg can come back into the lineup after missing his fourth game vs. the Red Wings, the odds are pretty good that Matt Bartkowski would be the odd defenseman out for the Black and Gold. Otherwise, the Bruins didn’t make any major changes at practice the day after their worst loss of the season. Julien had mixed around the forward line combinations at the start of the third period of the lopsided loss, but the lines were back to their familiar settings at practice on Thursday. Here are the line combos and D-pairings based on the Thursday practice:
