Toronto Maple Leafs center Mikhail Grabovski felt terrible the moment his swinging stick clipped Flyers captain Chris Pronger in an Oct. 24 game at the Wells Fargo Center.

He feels worse now.

Grabovski heard what originally was thought to be a scary right-eye injury has turned into prolonged concussion symptoms that ended Pronger's season and has his career in jeopardy.

"It's accident," Grabovski said from the Leafs dressing room Thursday following a morning skate that preceded his first game against the Flyers since Pronger's injury — a 4-3 Toronto loss. "I have so many shots in my face, too. A hundred percent, I didn't do it on purpose. I'm really kind of sad because (Pronger's) such a good player and it (maybe) finished his career. But it's an accident."
