Gorges missed Thursday's practice and isn't a sure bet to play Sunday against the Flyers, Mike Harrington of the Buffalo News reports.Though coach Ted Nolan termed Gorges' absence as a "maintenance day," his unwillingness to commit to the blueliner's availability for the team's next game suggests a legitimate injury might be in play. The Sabres will see if Gorges is able to get back on the ice for practice either of the next two days before revisiting his status.
