The Chiefs and quarterback Patrick Mahomes have reached agreement on a 10-year contract extension worth $450 million that ties him to Kansas City through the 2031 season, league sources told ESPN’s Adam Schefter.
The injury guarantee in the contract is $140 million, a source told 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 — $2.8 million this year, $24.8 million in 2021. The 10-year extension puts him under contract with the Chiefs for the next 12 seasons.
With a payout of at $477.6 million over the next 12 seasons, Mahomes will have the largest contract in American professional sports. Mike Trout had previously held that distinction when he signed a 12-year, $426.5 million contract with the Los Angeles Angels in March 2019. Trout’s contract is fully guaranteed, however.
Mahomes becomes the fourth quarterback since 2011 to receive an extension before the start of his fourth season, joining Ryan Tannehill (Miami Dolphins in 2015), Carson Wentz (Philadelphia Eagles in ’19) and Jared Goff (Los Angeles Rams in ’19).
The Chiefs had said they intended to sign their franchise quarterback to an extension but had previously indicated it might not happen until after this season.
Mahomes became the youngest quarterback to be named Super Bowl MVP, helping the Chiefs erase a 10-point fourth-quarter deficit by leading three touchdown drives. He finished 26-of-42 for 286 yards with three total touchdowns (two passing, one rushing), two interceptions and a 78.6 passer rating. He joined Tom Brady (Super Bowl XLIX) and Terry Bradshaw (XIV) as the only players to win Super Bowl MVP despite throwing multiple interceptions.
Mahomes was named the NFL MVP after the 2018 season, when he led the NFL with 50 touchdown passes and threw for 5,097 yards in his first full season as a starter.
The Chiefs traded up in the 2017 draft to select Mahomes with the 10th overall pick. He sat out for most of his rookie season behind starter Alex Smith, starting in only the season finale when the Chiefs rested their starters.
The Chiefs traded Smith to the Washington Redskins before the following season, making Mahomes the starter.
Overall, Mahomes has thrown for 9,412 yards with 76 touchdowns and 18 interceptions in 31 regular-season games. In five playoff games, he has thrown for 1,474 yards with 13 touchdowns and two interceptions.
