Brossoit allowed four goals on 19 shots in Tuesday's 4-3 loss to the Lightning.
With Robin Lehner (lower body) unavailable Tuesday, Brossoit drew a tough start and wasn't up to the challenge. The 28-year-old has rarely played that poorly this season. He owns a 6-3-0 record, a 2.72 GAA and a .904 save percentage through 11 contests. The Golden Knights aren't scheduled to play again until Monday versus the Avalanche -- that would be another tough draw for Brossoit if Lehner isn't healthy enough to play.
