DARLINGTON, S.C. – Kyle Larson’s No. 42 Chevrolet will be held for the first 30 minutes of Friday afternoon’s final Cup practice at Darlington Raceway.
Larson is being penalized because his car failed prequalifying inspection three times at Bristol Motor Speedway.
NASCAR added those three cars to the list of five more being held from final practice that were announced a few hours earlier.
The final practice session for Sunday’s Southerrn 500 will run from 3:30 to 4:55 p.m. ET on NBCSN.
