Kolosov will protect the home net in Saturday's preseason finale against Washington, Jackie Spiegel of The Philadelphia Inquirer reports.
Kolosov is poised to play the entire game. He went 0-2-0 while allowing eight goals on 47 shots in four appearances for Philadelphia during the 2025-26 regular season. If Dan Vladar (upper body) isn't ready for the start of the 2026-27 campaign, Kolosov could enter the year as Joseph Woll's backup.
