McCabe suffered a possible concussion Wednesday in the AHL and there is no timetable for his return, reports the Olean Times Herald. McCabe played in two games for the Sabres before being demoted. With Mark Pysyk sitting out with a heart-related issue, McCabe was first in line for a potential call-up, but now it looks like Chad Ruhwedel will be at the top of the list. McCabe will continue to be evaluated.
