Nashville acquired Posch and Ross Colton from Colorado on Tuesday in exchange for Magnus Chrona, a 2026 third-round pick and a 2027 third-round pick.
Posch posted a 15-8-5 record with a 2.78 GAA and an .891 save percentage over 28 regular-season appearances with AHL Colorado in 2025-26. He is under contract through the 2026-27 campaign, and he will probably spend most of the year in the minors.
