Jackson dealing with "significant sickness"

Ravens QB Lamar Jackson is dealing with a "significant sickness," NFL Network's Stacey Dales reports. "Truly a 50-50 chance he plays," Dales adds. Jackson just arrived to the stadium and is set to be evaluated by team doctors to determine whether he's able to play vs. the Bears today. We'll get word at 11:30 am ET. QB Tyler Huntley will start if Jackson can't.
