The Flyers continue to be stung by injuries to key players.
Top-line winger Matt Read, who led the Flyers with seven goals entering Thursday's game, will miss six weeks with a muscle tear in his ribs, the club announced.
Read was hurt late in the first period of Wednesday's 6-5 win in Pittsburgh.
Rookie Tye McGinn replaced Read in Thursday's lineup against Florida.
"You never like to see an injury," McGinn said before the game. "It's unfortunate, but I'm just going to go out and do my best. Keep working hard and stay positive."
Despite playing well in 13 appearances (three goals, plus-3), McGinn had been a healthy scratch in the previous two games.
