JOLIET, Ill. (AP) — Kurt Busch and Jimmie Johnson traded paint. It might be awhile until they exchange pleasantries.

Busch was fuming with Johnson after two of NASCAR’s top stars got into some late-race bumping Saturday night at Chicagoland Speedway that left each of them wondering if one has a problem with the other.

Johnson, though, seemed more ready to move on and let the incident slide.

Busch might still be upset when the Sprint Cup series picks up July 26 at Indianapolis.

Johnson had lost his lead to Denny Hamlin late in the race and fell back into three-wide racing with Busch and Jeff Gordon. Gordon appeared to get under Johnson, and the three-time defending Cup champion’s No. 48 Chevrolet got loose and made contact with Busch.

Angry at the contact, former champion Busch appeared to deliberately turn into Johnson. Their cars connected, causing a spark of excitement in a 400-mile race that Mark Martin won in mostly dominating fashion.

‘‘The No. 2 (Busch) and I touched and he bodyslammed me after that,’’ Johnson said.
