The Kansas City Chiefs and quarterback Patrick Mahomes have reached agreement on a 10-year contract extension 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. The 10-year extension puts him under contract with the Chiefs for the next 12 seasons.

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, 24, was named Super Bowl MVP after Kansas City's 31-20 victory over the San Francisco 49ers in Super Bowl LIV to become the first quarterback in NFL history to win a league MVP and Super Bowl before turning 25.

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.

He was named the NFL's 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, only starting in 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.
