PHILADELPHIA -- After surrendering a two-goal lead to the Philadelphia Flyers for the second time in less than a week, it was the New York Rangers who came out on top as Jaromir Jagr scored the decisive goal at 1:24 of the extra period to give the Rangers a 4-3 victory.

The Rangers re-captured the top spot in the Atlantic Conference from the Flyers who have now lost for the eighth time in their last 11 contests.

The victory may prove costly to the Rangers who lost rookie phenom Petr Prucha in the second period following a hit along the boards.

Prucha left the ice early in the second period following a hit by Flyers forward Turner Stevenson.

"I don't know what happened," said Stevenson. "I was just going for a hit and he stopped. I didn't even think I got a piece of him."

In 49 games with the Rangers this season, Prucha has 25 goals and 9 assists while leading the NHL with a 26.3 shooting percentage.

He is second on the team with 12 powerplay goals, two behind Jaromir Jagr.

Prucha, seen leaving the Wachovia Center on crutches, told reporters that he suffered an injury to the medial collateral ligament of his right leg.

According to Prucha, he will undergo a MRI tomorrow or Monday and preliminary estimates indicate that he will miss approximately 4-6 weeks pending the results of further diagnostic studies.

The 5-11 rookie was slated to represent the Czech Republic in the Turin Olympics later this month.

"Obviously, I feel bad," added Stevenson. "I'm not out there trying to hurt any kid. Hopefully he's alright."
