Green Bay Packers defensive end Micah Parsons pressured Chicago Bears quarterback Caleb Williams (18) last season.

Late October.

That might be the best guess as to when Green Bay Packers star defensive end Micah Parsons makes his 2026 debut.

Parsons, who suffered an ACL tear in Week 15 last season, had surgery for that injury, as well as a “clean up” of his meniscus, on Dec. 29, 2025. Parsons said the Packers employ a strict “nine-month rule” of no football when players are coming back from ACL/meniscus injuries at the same time.

That means if everything goes perfectly, the Packers would open Parsons’ 21-day window — one that allows a player to practice without counting against the 53-man active roster — in late September or early October. Green Bay players typically use all 21 days of that window, and if Parsons did the same, his first game back would be Oct. 25 at Detroit in Week 7.
