Seeler (knee) will miss Philadelphia's Opening Night against Vancouver on Friday, per Charlie O'Connor of PHLY Sports.
The Flyers are also set to play Saturday in Calgary, and it remains to be seen if Seeler will be an option for that contest. He had a goal, 13 points, 78 PIM, 132 hits and 205 blocks in 71 games with Philadelphia in 2023-24. Erik Johnson is projected to play Friday due to Seeler's absence.
