Gustavsson (illness) has been activated from injured reserve, Amalie Benjamin of The Boston Globe reports.
Analysis:
After being hospitalised for an elevated heart rate last Friday, Gustavsson was cleared to travel with the B's ahead of Thursday's game against the Sabres. However, a starter for that contest has yet to be named. His playing status should become clear once pre-game warmups begin, though it's worth noting that the Bruins have reassigned Malcom Subban to AHL Providence, further suggesting that Gus should be available Thursday.
