3:50pm: Barnes has indeed been placed on IR, per a team announcement. The move comes as no surprise, but it ensures Detroit will be without a key starter for a stretch. It will be interesting to see how Barnes’ recovery progresses and when he will become an option to return to action.
1:18pm: The Lions’ injury situation just keeps getting worse, with linebacker Derrick Barnes expected to be placed on injured reserve after sustaining a knee injury in Detroit’s Week 3 victory over the Cardinals on Sunday, per ESPN’s Jeremy Fowler .
Head coach Dan Campbell said that Barnes would be out for a significant amount of time, according to Dave Birkett of the Detroit Free Press . Barnes may even require surgery, making a stint on injured reserve an even more likely option as the team evaluates his knee and determines a long-term outlook for his recovery.
Barnes joins defensive end Marcus Davenport and center Frank Ragnow on the list of injured Lions coming out of Sunday’s game. Davenport suffered a season-ending elbow injury , while Ragnow tore his pectoral muscle .
“It’s going to hurt to lose Barnes,” said Campbell on Monday, but he emphasized that he has “a ton of faith” in the team’s remaining linebackers. He has multiple options to replace Barnes, who started the season alongside veteran Alex Anzalone and 2023 first-round pick Jack Campbell in defensive coordinator Aaron Glenn‘s 4-3 scheme. Malcolm Rodriguez , a 2022 sixth-rounder who became a fan favorite on Hard Knocks as a rookie, is the most likely candidate for Barnes’ spot, with Ben Niemann and Jalen Reeves-Maybin providing additional depth.
Barnes was a fourth-round pick by the Lions in 2021 who appeared in 32 games with 10 starts across his first two NFL seasons before earning a starting role in 2023 as the third off-ball linebacker behind Anzalone and Campbell. Landing on injured reserve will sideline Barnes until at least Week 8, though surgery could hold him out longer.
