Michal Neuvirth is day to day for the Philadelphia Flyers with a lower-body injury.
The 30-year-old goaltender was injured in the second period of a 2-1 victory against the Colorado Avalanche on Wednesday. He made 10 saves before he was replaced by Petr Mrazek.
Neuvirth is 9-7-3 with a 2.60 goals-against average and .915 save percentage this season.
Alex Lyon (4-2-1, 2.75 GAA, .905 save percentage) was recalled from Lehigh Valley of the American Hockey League on Saturday under emergency conditions.
The Flyers (39-25-14) hold the first wild card into the Stanley Cup Playoffs from the Eastern Conference. They host the Boston Bruins on Sunday (12:30 p.m. ET; NBC, TVAS, NHL.TV). Philadelphia is three points ahead of the New Jersey Devils, who hold the second wild card in the East, and one point behind the Columbus Blue Jackets for third place in the Metropolitan Division.
