Frozen Four participant signs with Sabres, makes debut
The Sabres signed undrafted rookie free-agent defenseman Chad Ruhwedel to a two-year contract after he completed his college career at UMass Lowell.
Hours after being signed Saturday, Ruhwedel made his NHL debut, playing in Buffalo's home game against the Flyers.
He had 23 points (seven goals) in 41 games this past season in helping Lowell reach the Frozen Four, before losing to Yale in a semifinal game on Thursday.
Overall, he had 63 points (15 goals) in 110 career games for the River Hawks.
The Sabres had an immediate need at defense. Tyler Myers will miss the remainder of the season after breaking his leg in a 5-1 loss to Montreal on Thursday.
Flyers forward Danny Briere returned after missing 10 games with a concussion.
Predators activate Forsberg
The Predators added forward Filip Forsberg to the active roster, and he may make his NHL debut against the Red Wings on Sunday.
The Predators gave Forsberg No. 9 on Saturday.
Forsberg was acquired in the trade that sent Martin Erat to Washington.
