Flyers goalie Ilya Bryzgalov was removed from Russia's roster after undergoing a medical exam, according to the Russian Hockey Federation's website.
The national team plays in the Channel One Cup tournament this week.
Vladimir Myshkin, the Russian national team coach, told Sovsport that Bryzgalov failed the medical exam because of a high fever.
Flyers general manager Paul Holmgren did not respond to a request for information.
Bryzgalov, who signed a nine-year, $51 million contract with the Flyers before last season, has been playing for CSKA Moscow during the NHL lockout. After a slow start, he has regrouped, lowering his goals-against average to 2.41 and raising his save percentage to .907 in 10 games.
Michael Leighton is the Flyers' backup goalie.
