Mason Lohrei returns to the Boston Bruins after a brief stint with the Providence (AHL). He was reassigned on Nov. 25 when defenseman Matt Grzelcyk returned from long-term injury reserve. This marks Lohrei's second call-up to the NHL, having been previously summoned on Nov. 1 when
Charlie McAvoy was suspended for four games, and Grzelcyk was placed on long-term injury reserve. In his initial ten NHL games, the 22-year-old rookie defenseman showcased promise with a goal and three assists.
