Poirier turned aside 11 of 12 shots during Saturday's 2-1 preseason win over the Blues.
Poirier drew the start during Saturday's preseason opener and was relatively effective over the first two periods before being replaced by Brandon Halverson. Despite Poirier's presence in the Dallas lineup, he'll likely begin the 2026-27 campaign in the minors after making 52 regular-season appearances with AHL Texas last year.
