BROOKLYN, MI - NASCAR officials say oil pans from three Joe Gibbs Racing cars were not submitted for approval before opening day inspection at Michigan International Speedway.
The three cars are driven by Denny Hamlin, Kyle Busch and Joey Logano.
Series director John Darby says all three teams changed their pans before Friday's practice, so their times will be allowed.
NASCAR says it will discuss early next week if there will be additional penalties.
On Monday, Busch was docked six points and his crew chief was fined $25,000 because his car failed post-race inspection at Pocono Raceway. The No. 18 Toyota was found to be too low during NASCAR's inspection Sunday.
