Pederson (upper body) won't play in Monday's preseason game against the Bruins, Kevin Kurz of The Athletic reports.
Pederson suffered an upper-body injury during the Flyers' preseason matchup against the Islanders on Sept. 21, and he'll be unavailable for a fourth consecutive exhibition matchup Monday. It's not yet clear when he'll be able to return, but it wouldn't be surprising to see him head to AHL Lehigh Valley once healthy.
