Gilmour has played in four games for Buffalo this season, recording five shots and averaging 17:03 of ice time per game.
He signed with the Sabres as a free agent on July 1. Gilmour spent the last three seasons as a member of the New York Rangers' organization. He was named to the 2018-19 AHL First All-Star Team after finishing the season among the AHL's top 10 defensemen in goals (2nd, 20), assists (8th, 34), points (2nd, 54) and game-winning goals (2nd, 5). He has recorded 105 points (32+73) in 190 career AHL games and five points (2+3) in 37 NHL contests.
Including Gilmour, Buffalo has nine defensemen on the roster. Zach Bogosian, who had offseason hip surgery, is close to making his season debut.
The Sabres are scheduled to practice on Saturday ahead of their game on Sunday against the Florida Panthers at BB&T Center. Faceoff is scheduled for 5 p.m. with the Buick Game Night pregame show starting at 4:30 on MSG.
