The Bears noted full-back Khalil Mack and wide receiver Allen Robinson as questionable for Sunday's Bills game.
Both returned to practice on Friday, but were limited. It was the same schedule that head coach Matt Nagy set up last week. At that time they sat on Wednesday and Thursday, the training sessions were limited, on Friday they were limited and did not play against the jets.
Mack has a right ankle problem while Robinson has a groin problem.
Defensive attack Bilal Nichols, who had missed two consecutive exercises with a knee injury, was also considered questionable.
Coach Matt Nagy said he expects all three to fly to Buffalo on Saturday.
As expected, guards Kyle Long (foot) and close Ben Braunecker (concussion) were excluded. Overseer Eric Kush, who was able to start in Long's place, did his full exercise after being limited to a neck injury the last two days. He will play Sunday.
