Just as NASCAR president Steve Phelps hinted at on Tuesday, officials announced where the extra races for Darlington and Charlotte were coming from on Friday when revealing the revised schedule for the season. This is the latest revised schedule since those additional races in the Carolinas were announced.

The following racetracks have had their events shifted: Chicagoland Speedway, Richmond Raceway (spring) and Sonoma Raceway. This apparently isn't even the final shift of the year, as another revised schedule for the 2020 season is expected to be released later.

"Due to the current pandemic, NASCAR has faced several difficult decisions, including realigning race dates from several race tracks," a statement from NASCAR statement read. "These decisions were made following thorough collaboration with local and state government officials from across the country, including the areas of the affected race tracks. We thank all our fans for their support, and we look forward to our return to racing."

Richmond's race scheduled for April 19 was moved to Darlington for May 20, but will keep its postponed Gander RV & Outdoors Truck Series race and its Sept. 11-12 race weekend. Here's the track's president speaking on this change.

"As a sport, we continue to be united in the best interests of the safety and well-being of our fans, competitors, stakeholders, and track personnel," said Richmond President Dennis Bickmeier. "There will be brighter and healthier days ahead in the greater Richmond region when NASCAR returns to Richmond Raceway for the NASCAR Playoff Race Weekend on Sept. 11-12. We look forward to NASCAR's best getting back on the track at Darlington Raceway on Sunday, May 17 as we launch a new countdown to the return of racing in RVA this fall."

Not everything has been so optimistic, however. At Chicagoland, the revised schedule that has come as a result of the coronavirus pandemic recently led the track to layoff a large portion of its staff.
