The Bears labeled Robinson doubtful Friday but will now remove him from the injury report.
Robinson suffered the concussion on Monday Night Football in a loss to the Los Angeles Rams to cap Week 7. The 27-year-old leads Chicago in receiving with 44 receptions for 544 yards and two touchdowns.
The Saints will be without their top receiver, Michael Thomas, who continues to nurse a hamstring injury. Thomas hasn't played since Week 1 due to an ankle injury, a disciplinary issue, and the hamstring ailment.
