❌ What didn’t happen:
The rumored four‑year, $68million pact signed March 3, 2025 appears to be unsubstantiated—originating from a single, low-credibility luxury blog article

That claim has no confirmation from reputable outlets like ESPN, AP, CBS, or via official team statements.

There have also been no recent updates to extend his contract beyond the 2027 end-date.

🔍 Context & outlook:
As of now, Decker is still under contract through 2027, tied directly to that 2024 three-year extension.

If in March 2025 the Lions had updated or extended the deal, trusted sources (Adam Schefter, Rapoport, team insiders) would already have reported it. They haven’t.

Given his age (31) and career mileage, a later extension remains plausible—but not yet on record.

📝 TL;DR:
✅ Confirmed: 2024 → 3yrs / $60M (through 2027).

❌ Unverified: Rumors of March 2025 → 4yrs / $68M — no credible reporting.
