Free agent quarterback Gardner Minshew reached agreement Thursday on a one-year deal with the Kansas City Chiefs, sources told ESPN's Adam Schefter.

Minshew will replace Carson Wentz as Patrick Mahomes' backup with the Chiefs. Wentz is a free agent.

The Las Vegas Raiders released Minshew on Wednesday, one year after signing him to a two-year, $25 million contract.

Minshew, 28, was in a tight quarterback competition with Aidan O'Connell during training camp last year before ultimately winning the starting job. But Minshew struggled in the starting role, passing for 2,013 yards, 9 touchdowns and 10 interceptions in 10 games -- nine starts -- before suffering a season-ending broken collarbone against the Broncos in November. The Raiders went 2-7 last season in the nine games Minshew started.

Minshew has 68 touchdown passes and 34 interceptions in 59 career games -- 46 starts -- over parts of six seasons with the Raiders, Indianapolis Colts, Philadelphia Eagles and Jacksonville Jaguars, who selected him in the sixth round of the 2019 draft.

His best season came in 2023, when he passed for a career-high 3,305 yards in 17 games -- 13 starts -- with the Colts as Indianapolis went 7-6 in the games he started.
