Sandstrom will guard the home crease in Monday's preseason game against the Red Wings, according to Mike Harrington of The Buffalo News.
Sandstrom will likely play out the 2024-25 season with AHL Rochester, so long as Buffalo's netminders remain healthy. The 27-year-old was 1-2-0 with an .823 save percentage and a 3.88 GAA in five regular-season appearances with the Flyers in 2023-24.
