Los Angeles Chargers linebacker Joey Bosa suffered a right foot sprain and is being placed on injured reserve, NFL Network Insiders Ian Rapoport and Tom Pelissero reported on Wednesday morning, per sources. Bosa has a chance to return this season, Rapoport and Pelissero added.
In a corresponding move, the Chargers are signing OLB Andrew Farmer II to the 53-man roster, Rapoport and Pelissero reported.
On Monday, head coach Brandon Staley told reporters that Bosa would likely being heading to injured reserve.
Bosa exited the Chargers' loss to the Packers on Sunday only four plays into the game, and was seen hopping off the field and going to his knees in pain on the sideline before riding the cart into the locker room while in tears. Bosa was later seen using crutches with a walking boot on the sidelines.
Bosa had just gotten healthy after playing through a broken toe earlier this season, even as he only missed one game with the injury. And now, Bosa will miss the next four games. It's a crushing blow to the Chargers' pass rush, which will miss its four-time Pro Bowl star headed down the stretch of the season.
If this marks the end of Bosa's 2023 season, he'll finish having played nine games (five starts), with 6.5 sacks, 20 tackles, eight QB hits and a forced fumble. After missing all but five regular-season games in 2022 due to groin surgery, it appears Bosa is set for a second straight year of significant playing time missed because of an injury.
