The Detroit Lions and linebacker Derrick Barnes have agreed to a three-year contract extension worth $25.5 million, with $16 million fully guaranteed at signing, according to a source who spoke with ESPN’s Jeremy Fowler.

Barnes, who has been a key part of the Lions’ defense, was limited to only three games last season after sustaining a knee injury in a Week 3 victory over the Arizona Cardinals. The 2024 campaign marked the first time in his four-year career that he did not play in at least 15 games. Despite the setback, the Lions have shown confidence in his abilities by securing him for the long term.

This move reinforces Detroit’s commitment to players who have been with the team since general manager Brad Holmes and head coach Dan Campbell took over in 2021. Barnes was selected by the Lions in the fourth round of the 2021 NFL Draft (113th overall) and has since established himself as an important contributor both on and off the field.

In addition to Barnes’ extension, the Lions have also re-signed veteran linebacker Anthony Pittman, according to Fowler’s report. Pittman, who initially played for Detroit from 2019 to 2023, briefly spent time with the Washington Commanders and Jacksonville Jaguars in 2024 before rejoining the Lions in December. He was signed off Jacksonville’s practice squad, reinforcing the team’s linebacker depth.

Detroit’s linebacker corps now includes Barnes, Jack Campbell, and Alex Anzalone, providing stability and continuity at the position. New defensive coordinator Kelvin Sheppard, who previously coached the team’s linebackers for the past two seasons, has played a significant role in Barnes’ development. Sheppard also served as the outside linebackers coach in 2021, further strengthening his connection with Barnes.

Throughout his four-year NFL career, Barnes has appeared in 51 games, starting in 26 of them. He has recorded 194 total tackles, four sacks, and eight quarterback hits. His versatility and strong presence on defense make him a valuable asset for the Lions moving forward.

The extension of Barnes’ contract signals Detroit’s commitment to building a strong defensive unit as they continue their efforts to remain competitive in the NFC. The decision to retain Barnes and Pittman ensures stability at linebacker while giving the team flexibility to develop its younger defensive talents.

By securing key contributors like Barnes, the Lions are showing their intent to maintain continuity in their defensive system under Sheppard’s guidance. As the team continues to improve, Barnes is expected to play a significant role in helping the defense become a more formidable force in the league.

With this extension, Barnes now has an opportunity to further solidify his place as one of Detroit’s defensive leaders. If he can stay healthy and build on his previous performances, he could play an instrumental role in helping the Lions achieve success in the upcoming seasons.
