PHILADELPHIA — All Danny Briere could hear were the agonizing screams. Chris Pronger buried his face in his hands after taking a brutal blow to the outside of the right eye, fearful of the worst for his eyesight.

Hunched over, Pronger skated straight to the bench, his hands over his eyes.

“I knew he was in trouble and needed help,” said Briere, who skated with Pronger to the bench.

Pronger, the Flyers captain, will miss two to three weeks and spend the next few days on bed rest, putting a scare in Philadelphia’s 4-2 win over the Toronto Maple Leafs on Monday night.

“He was hit on the side, and there’s a lot of swelling,” Flyers general manager Paul Holmgren said. “The hope is that there’s not a lot of blood buildup there where it will create issues.”

Pronger and Toronto’s Mikhail Grabovski sprinted for a loose puck in the circle after a rebound off Flyers goalie Sergei Bobrovsky in the first period. Grabovski slapped at the puck, but his stick connected with Pronger’s and the blade shot straight up into the defenseman’s face.

The injury overshadowed the first two goals of the season for Jaromir Jagr and Scott Hartnell. Jagr scored his first NHL goal since April 6, 2008. He left to play three seasons in Russia before signing a one-year deal with the Flyers. He split defenders on a breakaway, courtesy of a sweet feed from Claude Giroux, and flipped the puck past Jonas Gustavsson late in the first for the power-play goal.
