McCabe is currently recovering from an upper-body injury he suffered in Sunday's practice, Paul Hamilton of WGR Sports Radio 550 reports.
EDGE Analysis
McCabe is also currently fighting for an Opening Night roster spot with the Sabres in camp, so he'll want to return to action as soon as possible to avoid hurting his chances of doing so. McCabe was reportedly "already feeling better" on Monday, however, so it sounds like he won't miss much time with the ailment. The Sabres should update his status in the coming days.
