O'Reilly (mid body) is still considered day-to-day and could miss his second straight game against St. Louis.

EDGE Analysis

O'Reilly was a late scratch Saturday against New Jersey, and with the Sabres expected to make a few call-ups from AHL Rochester, it's possible he misses Tuesday's game. He's Buffalo's undisputed No. 1 center, averaging 21:46 TOI per game with nine points in 13 games, and against a deep St. Louis team his presence will be sorely felt. The Sabres have been ravaged by injuries this season, and thus far with so many players coming in and out of the lineup have not been able to establish much chemistry beyond Johan Larsson's line.
