Bears head coach Matt Eberflus confirmed Wednesday that Johnson remains in concussion protocol, Courtney Cronin of ESPN reports.
Johnson left last Thursday's win over Washington due to the head injury. The Bears will release their first Week 6 practice report later Wednesday, and if Johnson is able to take part in the session as at least a limited participant, it would be a sign that he's made some progression through the five-step protocol. The rookie running back is hoping to be available for the Bears' Week 6 game against the Vikings on Sunday, when he could be primed to take on a larger role with lead runner Khalil Herbert (ankle) likely to miss the contest.
