"He had a doctor’s appointment," Fox said to reporters assigned to cover the joint sessions in Foxborough. "So we keep evaluating him, keep looking and trying to make sure we cure all symptoms."
Miller was out of commission for 13 days after suffering a concussion on a hit near the goal line by linebacker Lamarr Houston on July 31, but he returned to practice over the weekend and traveled with the team to New England.
"He’s still coming off the concussion protocol," Fox explained. "We sent him to the doctor today. That’s why he wasn’t out here early at the start of practice. They were stuck in traffic."
Fox refused to call today’s developments a setback for Miller, who set career-highs in receptions (34), receiving yards (439), and touchdowns (five) for the Bears last season. Fox added there was no setbacks but no new prognosis.
