The Boston Bruins boosted an already prolific offense by acquiring Mammoth forward JJ Peterka on Friday, sending their 2026 first-round pick (No. 23) in the NHL draft and a 2028 first-round selection to Utah.

The Bruins had acquired the top-10 protected 2028 draft pick from Florida when Boston dealt star forward Brad Marchand to the Panthers in 2025.

Peterka, 24, played only one season with the Mammoth after coming over in a trade with the Buffalo Sabres after the 2024-25 campaign. Utah traded forward Josh Doan and defenseman Michael Kesselring to Buffalo last June and signed Peterka to a five-year, $38.5 million deal.

Peterka saw his point total drop from 68 in 2024-25 to 47 points (25 goals, 22 assists) despite playing all 82 games last season for the Mammoth. The Germany native's offensive downturn was partially due to receiving less ice time, from 18:11 to 15:59 per game.

A second-round pick of the Sabres in 2020, Peterka has 197 points (92 goals, 105 assists) in 320 career games with the Sabres (2021-25) and Mammoth. He joins a Bruins team that ranked 10th in goals per game (3.27) in 2025-26 and will play for Marco Sturm, the only German head coach in the league.
