Harris signed a one-year, $850,000 contract with the Bruins on Wednesday, per Elliotte Friedman of Sportsnet.
Harris had a goal and three points in four outings with AHL Providence as well as a goal and three points in eight appearances with Boston in the 2025-26 regular season. The 25-year-old blueliner will be in the mix for an Opening Night roster spot with Boston, but he will probably be a frequent healthy scratch if he does make the NHL team.
