Resolution criteria

• Resolves YES if, between Sep 7, 2025 and Feb 8, 2026 (inclusive), Christian McCaffrey is reported by a reliable source to have sustained an Achilles tendon tear/rupture (partial or complete) in either leg. Acceptable proof includes: a 49ers press release/news post, NFL.com report, or major outlet report (ESPN/AP/Reuters) confirming an MRI diagnosis or surgery, or the team placing him on IR with an Achilles tear designation. Otherwise NO. (49ers.com)

• “This season” = 49ers’ 2025 NFL regular season and postseason window: Week 1 began Sep 7, 2025; season concludes with Super Bowl LX on Feb 8, 2026. Preseason/training-camp injuries before Sep 7 do not count. (49ers.com)

• Exclusions: Achilles tendinitis, calf strains, “suspected” Achilles without later confirmation, or generic “lower leg” designations do not count. Market resolves on first clear confirmation. For examples of acceptable language (“MRI confirms torn Achilles”), see typical reporting standards. (reuters.com)

Background

• McCaffrey entered 2025 active for Week 1 after late‑week calf tightness; he dealt with Achilles tendinitis in 2024 and missed significant time. (reuters.com)

I will be closing this market prior to the start of each game and reopening afterwards if no injuries are suspected.
