NASCAR officials have canceled Friday’s on-track activity at Bristol Motor Speedway’s dirt track because of excessive rain. Two practice sessions were scheduled for each the NASCAR Cup Series and Craftsman Truck Series. However, showers at the .533-mile track and the forecast for more precipitation through the day forced the full cancelation. A NASCAR spokesperson said a revised schedule for the weekend would be released later Friday. The Cup Series is scheduled for its only event of the season on a dirt track in Sunday’s Food City Dirt Race. The Craftsman Trucks are scheduled for a Saturday show with the Weather Guard Truck Race on Dirt.
