Resolution criteria
Each answer is a specific NFL player for the 2025 season. It resolves YES if either:
The player’s team or the NFL publicly states he is “out for the season” due to injury, or places him on an injury-related reserve list (Reserve/Injured, Reserve/PUP, or Reserve/NFI) and he is not activated to the 53-man roster before his team’s season ends (including playoffs through Super Bowl LX on Feb 8, 2026). Verify via team releases and NFL.com’s 2025 Reserve List transactions. (panthers.com)
Preseason injuries count if they end the player’s 2025 season.
An answer resolves NO if the player returns to the 53-man roster or appears in any 2025 regular-season or postseason game after the injury. If a player returns to the game day roster but doesn't play, it still counts as returning.
Non-injury absences (suspension, holdout, retirement without injury) resolve NO.
Sources to use for resolution: NFL.com Transactions (Reserve List), official team announcements, and major outlets’ injury-status pages; IR rules: minimum 4 games; teams can return up to 8 players in the regular season (and up to 10 total with postseason). (nfl.com)
If reasonably official sources (team releases, Adam Schefter, etc) report a season ending injury, I'll go ahead and resolve "YES". I will not correct this if they return before the end of the season unexpectedly. If it seems in doubt, I'll leave the question unresolved.
Background
“Season-ending” is often confirmed either explicitly by a team or implicitly when a player remains on IR through the end of his club’s season; not every IR stint is season-ending because players can return after 4 games and within team return limits. (nfl.com)
2025 NFL season runs Sep 4, 2025–Jan 4, 2026; postseason concludes with Super Bowl LX on Feb 8, 2026. (en.wikipedia.org)
Feel free to add more players, I will NA any players added to the market after official announcements are already published. So if they go down on Sunday and then a report comes out Tuesday, I'd accept a new option on Monday but not Wednesday.
