O'Reilly is recovering from an appendectomy performed over the holiday break and currently has no timetable for his return.

EDGE Analysis

With 18 points (seven goals, 11 assists), O'Reilly is the fourth-highest scorer on a Sabres team currently sitting in the basement of the Atlantic Division standings. His absence leaves a gaping hole on the power play as well, as he had been manning the left wing on the top man-advantage unit with 10 points in that special teams situation this year. At the time of this writing, the Sabres have yet to call up a reinforcement to patch the lines without O'Reilly in tow.
