Porter (lower body) has been ruled out of Friday's matchup with Toronto, Mike Harrington of The Buffalo News reports.
The Sabres have yet to release any details regarding a potential timetable for Porter's return, but he'll miss Friday's contest at a minimum. The Michigan native hasn't seen regular-season NHL ice time since appearing in two games for Pittsburgh in the 2016-17 season. Porter has appeared in 124 games for AHL Rochester over the last two campaigns, logging 81 points (27 goals, 54 assists).
