Eye doctor says that Flyers defenseman Chris Pronger will not be cleared to play unless he wears a visor. Mikhail Grabovski stick alters how the Flyers' captain plays the rest of his career. That's how fast things can happen and Pronger is fortunate the injury was not worse. It could have been his career - and his eye. Initial diagnosis have Pronger missing perhaps two to three weeks. But until the swelling and blood in his eye dissipates, it is very difficult to gauge injuries of this nature and any lasting ill effects.
