Brisson was reassigned to AHL Henderson on Wednesday, per CapFriendly.
EDGE Analysis
Brisson had one goal and six shots on net over his first four NHL contests. The 22-year-old forward could be called up again if the Golden Knights want reinforcements -- it's unclear if his demotion is a signal one of the team's forwards like Michael Amadio (upper body) or William Carrier (upper body) could be ready to return from injury.
