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.

The Boston Bruins will be without Charlie McAvoy due to an undisclosed injury. Joe Sacco has explained the situation but hasn't delved into what caused it.

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.

Boston Bruins defenseman Charlie McAvoy is being shut down for a few games with a nagging injury, interim head coach Joe Sacco said Tuesday, per Boston Sports Journal's Joe Haggerty.The Bruins placed McAvoy on injured reserve amidst a flurry of moves.

Lindholm will miss his 29th straight game versus Tampa Bay on Tuesday, and landing on LTIR won't impact his recovery timeline. He has been skating, but it remains unclear when he will be ready to return to the lineup.

The Boston Bruins had good news and bad news this morning at practice at Warrior Ice Arena. Forward Mark Kastelic was back at practice in a non-contact red jersey.

The Boston Bruins are in a sticky situation heading into the second half of the season. They are in the playoff mix, but the gap is narrow. So, what should the Bruins do at the trade deadline?
