Philadelphia Flyers defenceman Kimmo Timonen is undergoing treatment for multiple blood clots in his native Finland and whether or not he will be able to return to the ice is unknown.
The 39-year-old Timonen has clots in his lower right leg and in both lungs, the team said in an announcement Tuesday.
Timonen experienced a problem with blood clots in 2008, missing four games of the Eastern Conference finals against the Pittsburgh Penguins before returning for Game 5 of the series.
"Flyers defenceman Kimmo Timonen has been diagnosed with blood clots in his lower right leg and in both lungs," Flyers general manager Ron Hextall said. "Kimmo is currently being treated for this disorder back in his home country of Finland. His return to play is yet to be determined."
Timonen, a 15-year veteran, signed a one-year, $2 million contract with the Flyers on June 13. He has spent the past seven seasons in Philadelphia. Before that, he was with the Nashville Predators for the first eight years of his NHL career.
Last season, Timonen played in 77 regular-season games for the Flyers and finished with six goals and 35 points.
