NASCAR has pushed the remainder of the Xfinity Series race on the streets of Chicago to Sunday morning due to the ongoing threat of lightning.
The race went on to a lightning hold with 25 laps completed and 30 still to run, and remained on pause for well over an hour while the series waited for the danger to clear. However as the clock ticked past 6:30pm local time and the potential for further lighting in the area remained ongoing, the decision was made to complete the race tomorrow morning at 10am central time. A postrace concert featuring The Chainsmokers was canceled.
