O'Reilly (undisclosed) did not skate Wednesday morning and may not suit up against Ottawa.

EDGE Analysis

No reason was given for O'Reilly's absence from the morning skate, but he's officially questionable against the Senators. It's been a trying year for the Sabres with injuries to key players and and O'Reilly's absence will create a huge void at center. He's averaging 22:17 TOI per game with eight points and 40 shots on goal in 12 games. His absence creates a favorable matchup for the Sens, although Evander Kane (ribs) will return to the lineup. Stay tuned for updates but for now consider O'Reilly a game-time decision.
