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:

The Bruins called up Matt Poitras from Providence on Tuesday, but the team also placed Charlie McAvoy on injured reserve.

Matthew Poitras is back with the Boston Bruins, but not under ideal circumstances. In addition to calling up Poitras and defenseman Michael Callahan from AHL Providence on Tuesday morning, the Bruins placed defenseman Charlie McAvoy and forward Mark Kastelic on injured reserve and moved defenseman Hampus Lindholm to long-term injured reserve.

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.
