Kastelic signed a three-year, $4.701 million contract extension with the Bruins on Friday.
Kastelic will complete the final campaign of his two-year, $1.67 million contract before this new deal will begin with the 2025-26 campaign. The 25-year-old forward has four goals, 11 points, 76 PIM and 151 hits in 39 outings. He's likely to continue to serve in a bottom-six capacity through the life of his new contract.
