The Bruins announced today that Jordan Szwarz has been recalled from Providence on an emergency basis.
Given that the team is heading west, he'll accompany them on the trip.
Because it's an emergency recall, he'll only play in the event of an injury. It's not quite clear yet who may be injured.
There's also a chance that he was recalled because someone on the team is nursing something minor and the Bruins want to have a fill-in ready to go during the trip.
