Buffalo Sabres center Ryan O'Reilly is questionable after re-aggravating a mid-body injury in a 2-1 overtime loss against the New Jersey Devils on Friday. O'Reilly did not play in a 2-1 loss against the Ottawa Senators on Wednesday because of the same injury. The Sabres did not conduct a morning skate on Saturday, so coach Dan Bylsma will update his lineup before the game. "It wasn't like he went into the game playing with the injury," Bylsma told the Sabres website. "He felt fine to go and I haven't talked to him other than to know he reaggravated it in the faceoff circle in the third period. Obviously it's day to day at this point. If he can't go [Saturday], with a day off Sunday and another day in-between, I don't see it lingering." Left wing Cole Schneider will play his second game of the season if O'Reilly is out. The Sabres, winless in their past three games (0-1-2), will conclude their second of a League-high 19 back-to-back sets this season. Buffalo recalled defenseman Justin Falk on Thursday for the first time since signing the unrestricted free agent to a one-year, two-way contact on July 1. He had one shot and one hit in 12:24 in his season debut on Friday.
