Kansas City Chiefs quarterback Patrick Mahomes has agreed to restructure his contract to pay him $210.6 million in guaranteed salary between this season and 2026, the most ever for an NFL player in a four-year span.

Escalators in his restructured deal could increase his total 2023-2026 compensation to $218.1 million, according to Ian Rapoport. The two-time Super Bowl champion and defending MVP signed a 10-year, $450 million extension with the Chiefs in 2020 that keeps him under contract through the 2031 season.

Mahomes’ original contract had incentives that could push his total compensation to $503 million, making it the largest athlete contract in American professional sports history.
