The Kansas City Chiefs are signing kicker Harrison Butker to a four-year, $25.6 million extension that includes $17.75 million guaranteed, sources told ESPN’s Adam Schefter on Monday.

The $6.4 million average of Butker’s new deal makes him the NFL’s highest-paid kicker, ahead of the Baltimore Ravens’ Justin Tucker and Philadelphia Eagles’ Jake Elliott, who both average $6 million per season with their contracts.

The deal ties Butker to the Chiefs through the 2028 season. Butker is scheduled to make $3.945 million in the final season of the five-year contract he signed with the Chiefs in 2019.

Butker confirmed in a post to X that he was finalizing a four-year extension.

“There’s no place I’d rather be than with the Chiefs, excited to finalize a 4 year extension,” he wrote. “To the Heights!”

Butker represented and negotiated the deal himself.
