The Detroit Lions have agreed to a four-year, $86 million extension with All-Pro safety Kerby Joseph, a source told ESPN's Adam Schefter on Wednesday.

The deal makes Joseph the highest-paid safety in NFL history with an average of $21.5 million per year. That surpasses the $21 million deal for Tampa Bay Buccaneers safety Antoine Winfield Jr. and the $19.1 million deal for Los Angeles Chargers safety Derwin James Jr.

Joseph will be entering his fourth season in the league after the Lions selected him in the third round of the 2022 draft.

He led the NFL with nine interceptions last season, tied for the most by any Lions player of the last 50 years (Jimmy Allen also had nine in 1981). That included a pick-six in a 24-14 win at Green Bay on Nov. 3. He also was third on the team with 83 tackles.

Joseph led the NFL in passer rating allowed in coverage last season. He also allowed the third-lowest completion percentage, according to Next Gen Stats.
