#00-Quin Houff, #24-William Byron, and #43-Erik Jones will drop to the rear of the field for the start of Sunday’s Ally 400 at Nashville Superspeedway.
All three penalties are for unapproved adjustments.
Houff and Jones each made contact with the wall on their qualifying laps and their teams had to make repairs.
Byron’s team was penalized for making a track bar change prior to their qualifying lap.
Bryon was scheduled to start 4th, Jones ninth, and Houff did not complete his qualifying laps so he was already starting last.
