Smith has missed the last four games with an upper-body injury but will be a game-time decision Tuesday vs. the Flyers. Smith would likely replace Matt Tennyson in the lineup.

Smith has appeared in all 44 games this season but will miss his firsts game on Tuesday. Will Butcher will draw into the lineup to replace him, including on the top power-play unit.

Bayreuther has appeared in 19 NHL games, all with the Dallas Stars, but will make his Blue Jackets debut in Florida. The 26-year-old defenseman has 10 points (1G / 9A) in 10 AHL games this season.

Hall was acquired from the Sabres on Sunday night and is expected to make his Bruins debut on Tuesday. Hall skated on the second line with David Krejci and Craig Smith and PP2 in Tuesday's morning skate.

Hall bet on himself with a one-year deal in Buffalo and it could not have gone worse. Hall registered just two goals with 17 assists (19 points) in 37 games. That doesn't paint the entire picture though, Hall has shot just 2.3 percent with a career-low 6.7 on-ice SH%, so there's certainly reason to expect him to post bigger numbers in Boston. Hall will almost certainly play on the second line with David Krejci.

Reilly is a solid bottom-4 defenseman that can provide some offensive punch, particularly on the power-play. With Charlie McAvoy and Matt Grzelcyk dealing with injuries, the Bruins were looking for some veteran insurance. The 27-year-old blueliner is still looking for his first goal of the season but has collected 19 assists in 40 games.

With the trade deadline less than a week away, the Sabres will keep Hall out of the lineup on Tuesday for precautionary reasons. With Hall out, look for C.J. Smith to draw into the Sabres lineup.

Gostisbehere has been a healthy scratch for the last three games but will replace Nate Prosser in the lineup on Monday. Gostisbehere has put up solid offensive numbers this season, with five goals and three assists in 20 games, but the Flyers are looking for more consistency on the defensive end.
