Flyers centre Matt Read will miss six weeks because of torn rib cage muscles.
Philadelphia general manager Paul Holmgren made the announcement Thursday night before the Flyers faced Florida. Read was injured on a hit by Chris Kunitz in the first period of Philadelphia's 6-5 win at Pittsburgh on Wednesday night.
Read leads the Flyers with seven goals, and his 13 points are third behind captain Claude Giroux and Brayden Schenn. He is the third Flyers player on the top line to get hurt this season, joining Scott Hartnell and Danny Briere.
Hartnell could return within 10 days, and Briere is already back in the lineup.
