It’s possible that the Bruins got on their team plane for the St. Louis-Dallas trip on Monday with just 18 skaters. With Andrew Peeke injured and still unavailable and Matt Poitras sent down to Providence, the varsity roster only had 18 players as of Monday afternoon.
But more than likely there’s at least one roster move coming. For salary cap reasons, there’s no need to make it official until Tuesday before the game.
