Redden took part in some of the Bruins' activities during their off day Saturday. His injury has not been disclosed. Coach Claude Julien called Redden's status a game-time decision, though the defenseman said he isn't quite ready to play.
"I'm coming," Redden said. "Good to be out there. I wasn't doing everything out there but still day-to-day and getting better. I'm just keeping patient and hopefully things keep progressing."
Game 2 is Sunday afternoon at the TD Garden.
"With Seidenberg obviously doing better, I don't anticipate him being ready for tomorrow but with the injury he's got you never know," Julien said. "As far as Ference is concerned he wasn't skating so he won't be able to go."
The Bruins started three rookie defensemen in Game 1 on Thursday night when they beat the Rangers 3-2 in overtime.
Ference has missed the last three games while Redden has missed the last two. Seidenberg injured himself early in Game 7 against Toronto last Monday and Saturday was the first time he skated.
