RFK Racing has withdrawn its appeal of last week’s penalty for a safety violation in the Cup Series race at Las Vegas Motor Speedway.

A NASCAR spokesperson confirmed Monday that the organization had dropped its appeal, six days after its No. 17 Ford team was docked for a detached wheel during the Pennzoil 400. Chris Buescher finished last in the event after his No. 17 entry crashed, and two crew members — jack operator Nicholas Patterson and front tire changer Jakob Prall — were suspended for two Cup Series races for the safety violation of Sections 8.8.10.4 A&C (Tires and Wheels; Loss or separation of an improperly installed tire/wheel from the vehicle during the event) in the NASCAR Rule Book.

By halting the appeals process, those suspensions are set to take effect for Sunday’s Food City 500 (3:30 p.m. ET, FOX, PRN, SiriusXM NASCAR Radio) at Bristol Motor Speedway, extending through the March 24 Cup Series event at Circuit of The Americas.

Patterson and Prall were on the over-the-wall crew’s roster last weekend for the No. 17 Ford, which Buescher drove to a runner-up finish Sunday at Phoenix Raceway. Team co-owner Brad Keselowski — Sunday’s fourth-place finisher — indicated that the penalty appeal was intended to provide extra time to get new crew members better acclimated to their fill-in roles.
