The Kansas City Chiefs have agreed to a five-year contract extension with kicker Harrison Butker worth $20 million, according to a source.
The $4 million annual average on the extension would tie him for eighth among the league\'s highest-paid kickers.
Butker, 23, has made 62 of 69 field goal attempts since joining the Chiefs.
His 90 percent success rate is ninth best in the league for kickers with at least 10 attempts.
