O'Reilly's injury has been reclassified as an oblique problem and he's at about 70% health right now, ruling him out of Thursday night's contest against the Lightning, Paul Hamilton of WGR Sports Radio 550 reports.

EDGE Analysis

At this point, there hasn't been an official timetable given for O'Reilly's return so it's tough to say when he'll return to the lineup for sure. This will be the third consecutive game he misses to the injury after aggravating it against the Devils on Nov. 11, so the Sabres might want to take their time and make sure he gets healthy for sure this time. Look for Sam Reinhart and Johan Larsson to step up while O'Reilly remains out.
