Vanecek was placed on waivers Sunday with the intention of assigning him to AHL Hamilton.
Vanecek posted a 5-13-3 record with one shutout, a 2.94 GAA and an .883 save percentage in 22 appearances with Utah during the 2025-26 regular season. He signed a one-year, $1 million contract with the Islanders when free agency opened in July. If he goes unclaimed, he will likely begin the 2026-27 campaign in the minors.
