The Kansas City Chiefs and quarterback Patrick Mahomes have reached agreement on a 10-year contract extension worth over $400 million total that ties him to Kansas City through the 2031 season, league sources tell ESPN's Adam Schefter.
The Chiefs picked up Mahomes' fifth-year option for the 2021 season in April, putting him under contract for the next two seasons. Mahomes had two years and $27.6 million left on his existing deal -- $2.8M this year, $24.8M in 2021. The 10-year extension puts him under contract with the Chiefs for the next 12 seasons.
