BUFFALO, N.Y. (AP) - Buffalo Sabres starting goalie Robin Lehner is sidelined with an illness, which means backup goalie Anders Nilsson will make his season debut at Philadelphia on Tuesday night.

Coach Dan Bylsma provided the update after Lehner missed practice Monday. Bylsma said Lehner was "feeling under the weather," and not scheduled to travel with the team.

Buffalo will fill the backup spot by calling up a player from its American Hockey League affiliate in Rochester.

Lehner has 1-2-1 record in playing all four games this season.

Buffalo gave up a fifth-round pick in the 2017 draft to acquire Nilsson in a trade with St. Louis in July.

He has a 19-22-4 record over three NHL seasons split between three teams, including the New York Islanders and Edmonton Oilers.
