The most noteworthy among those was putting Charlie McAvoy on injured reserve leaving their already thin defense significantly thinner. They also put Mark Kastelic on injured reserve and moved Hampus Lindholm to long term injured reserve. The Bruins summoned Matt Poitras and Michael Callahan from Providence.
