Chicago Bears edge rusher Khalil Mack has been placed on injured reserve after undergoing foot surgery, effectively ending his 2021 season, NFL Network’s Ian Rapoport reported on Friday.
Mack had previously missed the two most recent games prior to the Bears’ bye week due to the foot injury, but he had not been placed on the injured reserve until now, thus taking up a roster spot despite not playing in any games. Chicago added veteran edge rusher Bruce Irvin to their practice squad on Thursday, which signaled their lack of confidence in Mack’s return for the foreseeable future.
