The Sabres made a roster move on Sunday, demoting defenseman Zac Jones and recalling winger Isak Rosen. Blueliner Jacob Bryson skated over the weekend and has been activated from injured reserve. Rosen, who has an impressive 20 goals in 28 games with AHL Rochester, has contributed at the NHL level playing higher in the lineup, with seven points (3 goals, 4 assists) in 13 games.Â
