With Marc Gatcomb clearing waivers and being sent to Bridgeport (AHL) , New York has recalled Marshall Warren in a corresponding move. The 24-year-old defensemen has yet to appear in the NHL after joining the Islanders from the University of Michigan (NCAA) in 2023-24. He's earned his promotion due to his hot start to begin 2025-26, with two goals and five points in four games with Bridgeport.

Warren was the 166th pick of the Minnesota Wild in the 2019 NHL Entry Draft. He has spent the last several seasons playing collegiate hockey, most recently recording 18 points (4G / 14A) in 41 games with the University of Michigan this season.
