Chris Pronger's progress from a broken right hand is "not as fast as we thought," and the defenseman probably will not play again in the regular season, general manager Paul Holmgren said after Thursday night's 1-0 loss to Atlanta.

Pronger, 36, did not participate in the Flyers' morning skate on Thursday.

Originally, the Flyers had hoped Pronger would play against Buffalo next Friday and the Islanders on April 9, the final two regular-season games.

Holmgren said Pronger "probably pushed it a little bit too quickly in the rehab" and said it was a "minor setback."

The general manager said he expected Pronger to be healthy for the playoffs.

While Pronger's recovery has gone slowly, winger Jody Shelley is making quicker-than-expected strides from March 24 orbital-bone surgery, and Holmgren said he may play next week.
