Vancouver acquired Brannstrom from Colorado on Sunday in exchange for Tucker Poolman (head) and a 2025 fourth-round draft pick.
Brannstrom signed a one-year, $900,000 contract with the Avalanche in July after Ottawa declined to issue him a qualifying offer. The 25-year-old defender had three goals, 20 points, 77 shots on net and 111 blocked shots in 76 games with the Senators in the 2023-24 regular season. Following the trade, Brannstrom was placed on waivers with the intent to assign him to AHL Abbotsford.
