Boston will keep one of its defensive depth pieces after it announced on Sunday that the Bruins had re-signed Michael Callahan to a one-year, two-way contract extension. The 25-year-old appeared in 17 games with the Bruins in 2024-25, picking up a goal, nine SOG and a -5 plus/minus. He is expected to fight for one of Boston's final defence spots in training camp.
