NOTES

Panthers: Florida assigned reserve goaltender Dan Ellis to the team’s AHL affiliate in San Antonio.

The move means that, as expected, Al Montoya is set to begin the season as the backup to Florida starter Roberto Luongo.

Predators: Nashville signed restricted free agent forward Taylor Beck to a one-year, $550,000 deal.

Beck, 23, has played 23 career NHL games over the past two seasons with Nashville, and he has seven points.

Sabres: Forward Matt Ellis was among seven players Buffalo assigned to its AHL affiliate in Rochester, New York.

Ellis and defenseman Drew Bagnall, who was also demoted, must first clear waivers.

Also assigned to the minors were forwards Joel Armia, Buffalo’s 2011 first-round draft pick, and Tim Schaller, defenseman Nick Petrecki and goalies Nathan Lieuwen and Andrey Makarov.
