The Utah Mammoth pulled off a blockbuster trade Wednesday night, acquiring JJ Peterka from the Buffalo Sabres.

Utah acquired forward J.J. Peterka from the Buffalo Sabres in exchange for defenseman Michael Kesselring and forward Josh Doan. Peterka, who would’ve been a restricted free agent, agreed to a five-year, $38.5 million contract extension ($7.7 million average annual value) with the Mammoth as part of the trade.

The 23-year-old Peterka is coming off consecutive 25-plus goal seasons, including 27 this year with a career-best 68 points in 77 games.
