The Chicago Bears placed standout safety Jaquan Brisker on injured reserve Thursday, keeping him sidelined for at least four more games as he recovers from a concussion he sustained earlier in the season.

The 2022 second-round draft pick has missed the last four games with a concussion he suffered against the Panthers in Week 5. He'll miss at least the next four games.

Brisker, 25, has been in the NFL's concussion protocol since Oct. 7 after he sustained injury while forcing a turnover in a 36-10 win over Carolina in Week 5. The safety reported concussion-like symptoms one day after the Panthers game and did not travel with the Bears to play in London.
