Report: Richard Childress and Kyle Busch in altercation

KANSAS CITY, Kan. -- After Saturday's Camping World Truck Series race at Kansas Speedway, word spread that Richard Childress and Kyle Busch were involved in an altercation in the garage after Busch and Childress driver Joey Coulter battled for fifth place late in the race.

Speed pit reporter Ray Dunlap tweeted that Childress "put a whipping" on Busch after the race.

Hot news from the track. Grandpa Childress put a whipping on Kyle Busch in the truck garage. Look for big sun glasses on kubu sun.

Shortly thereafter, SPEED Center, SPEED's racing recap show, posted this on Facebook:

CHILDRESS vs. KYLE BUSCH: multiple witnesses tell SPEED there was a physical confrontation between Richard Childress and Kyle Busch after today's NASCAR Truck Series race

The incident took place in the garage area. Childress initiated the conflict, first taking a swing at Busch, then put him in a headlock. NASCAR spokesman Kerry Tharp said that the sanctioning body was looking into reports of the altercation.

Busch was battling Childress driver Joey Coulter for fifth place late in the O'Reilly Auto Parts 250. The racing seemed clean as Coulter and Busch didn't make contact as they were side by side, but Busch gave Coulter a door slam after the race, potentially sparking what has been reported.

Busch is on probation through June 15 in all NASCAR series for an incident with Kevin Harvick -- a Childress driver in the Sprint Cup Series -- at Darlington when Busch ran into Harvick's car after Harvick got out to confront him on pit road after the race.
