Tempers flare at Kentucky Speedway after Friday night's Xfinity race and punches are thrown between Harrison Burton and Noah Gragson on pit road.

It took place after Gragson’s No. 9 JR Motorsports Chevrolet got into the rear of Burton’s No. 20 Joe Gibbs Racing Toyota while battling for position.

Both clipped the wall before Gragson finished seventh and Burton took 12th.
