According to CSN Philly's Tim Panaccio, Voracek suffered a severely sprained knee in Europe. Whether or not that will affect the Flyers remains 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 year and played well. In 78 games in 2012, 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.
Voracek has been playing well in the KHL, racking up seven points in as many games while he waits for the lockout to end. The Czech native is one of seven Flyers who are currently playing overseas.
