The race will be the first Cup Series race held on dirt since Richard Petty won the 1970 Home State 200 at the State Fairground Speedway in Raleigh, N.C.
The dirt race is one of several shakeups coming to the 2021 schedule.
NASCAR has dropped Chicagoland and Kentucky from the schedule, while adding the Road America and Circuit of the Americas courses in Wisconsin and Texas. It’s also ending the Brickyard 400 after 27 races and switching to the Indianapolis Motor Speedway infield road course.
Nashville Superspeedway’s first-ever Cup Series race is scheduled for June 20 and Atlanta and Darlington will have two weekends each.
Michigan is losing one race and so is Texas Motor Speedway.
All of the races will be held on weekends because of disappointing TV ratings for the mid-week races that took place this year.
