Joe Gibbs Racing driver Matt Kenseth, one of 12 drivers in the Round of 12 of the Chase for the NASCAR Sprint Cup, will start Sunday's Bank of America 500 (noon ET, NBC, PRN, SiriusXM NASCAR Radio) at Charlotte Motor Speedway from the rear of the field for unapproved adjustments.
The No. 20 Toyota was forced to make pre-race changes due to repairs made for a trackbar mount, according to the team. His car went through the inspection process multiple times.
Kenseth qualified 17th, but will fall back to 40th during pre-race warm-up laps.
All points in the driver standings were reset prior to this round, so all 12 drivers enter Charlotte with 3,000 points.
The Bank of America 500 will start on a green race track, necessitating a competition caution at Lap 25. The final two Sprint Cup Series practices, scheduled for Friday, were canceled due to rain. The race was slated to run Saturday night, but also was pushed back a day due to weather.
