Ryan Sieg’s 14th-place finish in Saturday’s Xfinity Series race at Las Vegas Motor Speedway was disqualified by NASCAR after his No. 39 Chevrolet failed heights in post-race inspection. The car was found to be too low in the right and left front.
Sieg is now credited with a last-place finish.
The disqualification does not impact Sieg’s playoff eligibility or his seeding. He will start the playoffs in 11th with 2,001 points.
As a result of the disqualification, Ryan Truex is the new 14th-place finisher.
Sieg’s disqualification is the fifth time that has occurred this season in the Xfinity Series.
Denny Hamlin had a win at Darlington taken away and given to Cole Custer after his car failed heights.
Christopher Bell had his third-place finish at Chicagoland Speedway in June taken away when his car failed inspection. His car was found to be too low in the front and too high in the rear.
Kaulig Racing has twice had AJ Allmendinger’s car disqualified. The car was disqualified after Allmendinger’s third-place finish at Daytona in July when inspection showed that the engine would not hold a vacuum. Allmendinger’s second-place finish was taken away when his car failed to meet minimum height requirements at Watkins Glen.
