What happened: San Francisco opened this week's SAP Trivia Tuesday with a signed Christian McCaffrey football as the prize. Fans must go 10-for-10 for a chance to win.

Why it matters: McCaffrey remains the central star of the San Francisco offense in the 2026 regular season. Weekly prizes sustain fan engagement between gamedays without affecting roster or standings.

What to watch: Entries run through the weekly SAP link before next Tuesday's edition resets the contest.
