The approach of Tropical Storm Hanna has forced NASCAR officials to postpone Saturday night's Sprint Cup Series race at Richmond International Raceway.
The Chevrolet 400 is now scheduled to be run at 1 p.m. Sunday. The race will finalize the field of 12 drivers who will be eligible to compete for the 2008 series championship.
Meanwhile, the Nationwide Series race scheduled for Friday night has been moved to Sunday at 7 p.m.
NASCAR says the field for both races will be set based on driver's standings and that the garage will be closed and the cars impounded until 7:30 a.m. Sunday.
