PHILADELPHIA -- Flyers defenseman Kimmo Timonen will likely miss the Eastern Conference finals against the Pittsburgh Penguins because of a blood clot in his ankle.

Philadelphia general manager Paul Holmgren said Timonen was hit with a shot in Game 4 against Montreal. The Flyers won that series in five games and will open the next series at Pittsburgh on Friday night.

"We have to view this that he's not a player for us in the series, and march on," Holmgren said Thursday night.
