The Los Angeles Rams and Jalen Ramsey have agreed to terms on a five-year, $105 million extension that is the largest contract ever for a cornerback, agent David Mulugheta told ESPN’s Adam Schefter.

Ramsey becomes the first defensive back in NFL history to sign a deal worth over $100 million, and his $71.2 million at signing is the largest guarantee to a defensive back.

The Rams announced the five-year agreement Wednesday without providing the value.

An All Pro and three-time Pro Bowl selection, Ramsey becomes a long-term fixture on a defense that includes two-time NFL Defensive Player of the Year Aaron Donald, who signed a six-year, $135 million extension before the 2018 season.

Ramsey is the fourth player since 2018 whom the Rams have signed to a record-breaking extension, including Donald, quarterback Jared Goff and former running back Todd Gurley, whom they cut in March.
