RFK Racing suspensions on hold as team appeals Las Vegas penalty

RFK Racing appealed NASCAR's penalty to the No. 17 team for a detached wheel during last Sunday's Cup Series race at Las Vegas Motor Speedway. The team asked for a deferral of the suspensions of two crew members while the penalty was under appeal, which NASCAR granted on Thursday.
Chris Buescher finished last in Sunday's Pennzoil 400 after his right-front wheel became unfastened, and his crash into the outside retaining wall forced a caution period in the 28th of 267 laps.
As a result of 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, No. 17 crew members Nicholas Patterson (jack) and Jakob Prall (front tire changer) were suspended for two Cup Series events, which is now pending the appeal.
