As expected, the Bears on Thursday placed center/guard Lucas Patrick on injured reserve with a toe injury that forced him to exit Monday night's win over the Patriots in the first quarter.
Patrick must miss at least four games, making him eligible to return for the Bears' Nov. 27 road contest against the Jets.
Patrick signed with the Bears in March after spending his first six NFL seasons with the Packers, appearing in 73 games with 34 starts. He became a regular starter in 2020, opening 15 contests at guard. Patrick split time between center and guard in 2021, appearing in all 17 games with 13 starts.
The Bears on Thursday also made two practice-squad moves, signing defensive end Gerri Green and releasing receiver Reggie Roberson.
Green was selected by the Colts in the sixth round of the 2019 draft out of Mississippi State. He had two stints with Indianapolis in 2019-20 when Bears coach Matt Eberflus was the team's defensive coordinator.
Green has spent time on the practice squad with the Colts, Patriots (2019), Commanders (2020), Raiders (2020-22) and Titans (2022) but has yet to play in an NFL regular-season game.
