The NASCAR Cup Series has reached its elite eight after four more drivers were eliminated from championship contention.

Former series champions Kyle Busch and Brad Keselowski were bounced from the playoffs along with 2022 runner-up Ross Chastain and Bubba Wallace following Sunday’s race on the Roval at Charlotte Motor Speedway, won by AJ Allmendinger.

Eight drivers now move on to the three-race third round, seeking a berth in the final four, where one race will decide the 2023 champion. William Byron, who leads the series with six wins in 2023, tops the standings with the points reset to begin the round.

The Round of 8 kicks off with two intermediate ovals – Las Vegas Motor Speedway and Homestead-Miami Speedway – before a final elimination race at NASCAR’s oldest and smallest track, Martinsville Speedway.
