Two crew members of the No. 43 Legacy Motor Club team have been suspended for two NASCAR Cup Series races following the Oct. 20 race at Las Vegas Motor Speedway, NASCAR officials announced Tuesday.

The right-front wheel of the No. 43 Toyota driven by Erik Jones detached from the vehicle after a pit stop at Lap 70 during the first caution period of the South Point 400. A lost wheel violates Sections 8.8.10.4.A & C in the NASCAR Rule Book, which concerns the “loss or separation of an improperly installed tire(s)/wheel(s) from the vehicle.” Jones ultimately finished 25th in the 267-lap event.

Because the tire came loose on the racing surface, suspensions were dealt to front tire changer John Rosselli and jackman Kellen Mills, both of whom will be eligible to return for the final race of the season on Nov. 10 at Phoenix Raceway.

Following Saturday’s NASCAR Xfinity Series race, three teams were found each with one loose lug nut, a violation of Section 8.8.10.4.A in the Xfinity Series Rule Book, which states “all five lug nuts must be installed in a safe and secure manner during the event.” As a result, three crew chiefs were fined $5,000 each for their respective team’s infractions:

• No. 00 Stewart-Haas Racing crew chief Jonathan Toney

• No. 27 Jordan Anderson Racing crew chief Shane Whitbeck

• No. 38 RSS Racing crew chief Kevin Johnson
