Vegas wheel infractions bring penalties for Busch, Briscoe teams

Today at 11:27 AM

Joe Gibbs Racing and Richard Childress Racing were issued crew member suspensions Wednesday for wheels that became detached from their vehicles at Las Vegas Motor Speedway.

Chase Briscoe lost the left rear from his No. 19 Gibbs Toyota on lap 33 after an early round of pit stops. Briscoe was given a two-lap penalty during the race and his jackman (Caleb Dirks) and rear tire changer (Daniel Smith) are suspended for the next two Cup Series races at Homestead-Miami Speedway and Martinsville Speedway. Briscoe rebounded from the penalty to finish on the lead lap in the 17th position.

Busch lost the right-rear wheel from his No. 8 Childress Chevrolet on lap 113. It was on the green flag lap of a restart after the field had made pit stops. Busch got sideways off Turn 2 as the wheel was coming off and hit the wall, which resulted in the car needing repairs in the garage before returning to the race. He finished 33rd. The jackman for Busch (Dylan Moser) and rear tire changer (Shiloh Windsor) have been suspended for the next two races.

Additionally, NASCAR issued fines to four Xfinity Series teams for loose lug nuts after Saturday afternoon's race at Las Vegas. Those were the No. 11 team from Kaulig Racing, No. 19 team of Joe Gibbs Racing, No. 26 team from Sam Hunt Racing, and the No. 88 team from JR Motorsports. There was one Craftsman Truck Series team fined for the same infraction, which was the No. 07 team from Spire Motorsports.

Two crew members were also indefinitely suspended for violations of the substance abuse policy. The first was Josiah Wright, who was listed as the rear tire changer for Brad Keselowski, and the second was Corbin Sklener, who has worked with GK Racing and Mike Harmon Racing.
