Tinoisamoa had a recurring soreness in his right knee, a byproduct of two significant injuries in the same area last year, and missed practice on Wednesday, was limited Thursday and did not participate at all on Friday according to ESPN Chicago.
Nick Roach will start in Tinoisamoa’s place.
The only other player listed on the Bears injury report this week was wide receiver Rashied Davis, who was limited with a shoulder injury. Davis wasn’t listed Friday, however, so should be good to go on Sunday.
The Lions injury report listed both starting quarterback Matthew Stafford and backup Shaun Hill as out for Sunday’s matchup while defensive end Kyle Vanden Bosch is questionable.
