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.

The previous largest contract for a cornerback in terms of average annual value was the $18.2 million per year given to Darrelle Revis in 2013 when he signed a six-year contract after being traded from the New York Jets to the Tampa Bay Buccaneers. Revis was released the following offseason.

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.
