There were 39 cars on the entry list for the NASCAR Cup race at Chicagoland Speedway, which is the first NASCAR event at the track in seven years. Among those were three open teams: the No. 67 23XI Racing Toyota of Corey Heim, the No. 44 NY Racing Team Chevrolet of J.J. Yeley, and the No. 66 Garage 66 Ford of Josh Bilicki.
However, the Carl Long-owned No. 66 announced on Thursday that they would be withdrawing from the event, bringing the entry list down to 38 cars.
