Following teardown inspection at the R&D Center in Concord, North Carolina, NASCAR has issued the No. 22 team of Team Penske an L1-level penalty for a rear suspension violation.

The penalty makes Logano's victory in the Toyota Owners 400 is encumbered, meaning the team will not be allowed to use the victory for qualification in the Monster Energy NASCAR Cup Series Playoffs. If Logano qualifies for the postseason, he will not receive the five playoff points associated with the win.

In addition to the loss of automatic playoff consideration, NASCAR has fined crew chief Todd Gordon $50,000 and suspended him for two races. Logano was docked 25 championship driver points and the team was docked 25 owner points.

Logano's No. 22 Ford was found to be in violation of Section 20.14.2 of the NASCAR rule book, which rules over the trailing arm spacers and pinion angle shims.

NASCAR also issued a penalty to the No. 11 team of Denny Hamlin after a lug nut was missing in post-race inspection. Crew chief Mike Wheeler has been fined $10,000 as a result of that violation.

In the Xfinity Series, NASCAR penalized Richard Childress Racing crew chief Danny Stockman Jr. after the No. 21 car was found to have two lug nuts installed improperly after the Toyota Care 250. He was fined $10,000 and is facing a one-race suspension.
