The Boston Bruins announced a series of transactions Tuesday, placing defenseman Charlie McAvoy and forward Mark Kastelic on Injured Reserve (IR), defenseman Hampus Lindholm on Long-Term Injured Reserve (LTIR) and recalling forward Matt Poitras and defender Michael Callahan from the AHL’s Providence Bruins.

BOSTON — Bruins interim coach Joe Sacco had plenty to sort out when he met with the media after morning skate ahead of Tuesday’s game against the Lightning at TD Garden. Two players were called up, two were placed on injured reserve and a third was moved from injured reserve to long-term injured reserve. Sacco explained:

Boston Bruins forward Mark Kastelic was on the ice again yesterday but isn’t ready to play just yet. Joe Haggerty: Bruins defenseman Hampus Lindholm was skating on his own for the second consecutive day.
