Five-time Pro Bowl defensive end Joey Bosa reached agreement Tuesday night on a one-year, $12.6 million deal with the Buffalo Bills, a source told ESPN's Adam Schefter.

The Los Angeles Chargers released the 29-year-old Bosa on Wednesday, cutting ties with their longest-tenured player and one of the best in franchise history. After making four Pro Bowls in his first six seasons, he has been plagued by injuries since but was selected to his fifth Pro Bowl in 2024, albeit as an alternate.

Bosa immediately becomes a starter for the Bills' defensive line, joining defensive end Greg Rousseau, who was signed to a four-year extension Saturday. The Bills released pass rusher Von Miller on Sunday, saving $8.4 million in cap space. Miller was signed to a six-year deal in the 2022 offseason with the hope that adding an experienced and accomplished pass rusher would help boost the Bills' defense.

In adding Bosa, a player who will be 30 when the season begins and has dealt with injuries, there are similarities to the Miller signing, although the one-year deal is a stark difference. The Bills began addressing the D-line Monday by agreeing to a three-year deal with former Los Angeles Rams defensive end Michael Hoecht.

Defensive line was a need for the Bills this offseason, with getting after the pass rusher an issue for the team at times, as spotlighted in the AFC Championship Game loss to the Kansas City Chiefs. Bills general manager Brandon Beane emphasized this offseason that the team believes in building from the lines, and he has not been shy about investing in the group while also not spending too much money to forfeit future seasons.

Bosa's deal is the latest move in what has been a busy offseason for the Bills, who also have reached extensions with wide receiver Khalil Shakir, linebacker Terrel Bernard and quarterback Josh Allen. The Bills have agreed to terms with outside free agents wide receiver Joshua Palmer and Hoecht, as well.

The No. 3 pick in the 2016 draft, Bosa was NFL Defensive Rookie of the Year that season, posting 10.5 sacks and 17 tackles for loss. He set an NFL record by recording 19 sacks in his first 20 games.

The Chargers rewarded Bosa with a five-year, $135 million contract extension in 2020, a deal that at the time was the richest for a defensive player in NFL history. But he has played in just 28 games over the past three seasons due to injuries.

For his career, Bosa has totaled 343 tackles, 157 quarterback hits, 87 tackles for loss, 17 forced fumbles and 4 fumble recoveries in 107 regular-season games. His 72 career sacks rank second in Chargers history, behind only Leslie O'Neal (105.5).
