According to CSN Philly's Tim Panaccio, Voracek suffered a severely sprained knee in Russia. Whether or not that will affect the Flyers reamins to be seen with the NHL lockout firmly in place, but it certainly isn't positive.
The following statement was released by HC Lev Praha:
"Centre Jakub Voráček suffered a knee injury in the third period and early indication is he´ll be out of the lineup about four weeks."
Voracek was acquired from the Columbus Blue Jackets as part of the Jeff Carter trade last summer and played well in his first Philadelphia season. In 78 games in 2011-12, Voracek tallied 49 points (18 goals, 31 assists) to accompany a +11 rating. The 23-year-old was even more impressive in the postseason, scoring 10 points in only 11 contests. He's expected to replace Jaromir Jagr on the Flyers' top line with Claude Giroux and Scott Hartnell when and if the NHL season begins.
Voracek has been playing well in Russia, racking up seven points in as many games while he waits for the lockout to end. The Czechoslovakia native is one of seven Flyers who are currently playing overseas.
