Due to the forecast for rain, high winds and rapidly falling temperatures, officials at the Knoxville Raceway Saturday morning made the announcement to cancel opening night. It was supposed to be the 70th Season Opening night, but it will now be during the two night World of Outlaws Nos Energy Drink Sprint Cars making their first April visit to the raceway in several years. Coverage of the Extreme Powered by Mediacom Showdown will be on KNIA Friday and Saturday with Live Track Side at 5:00 and Race Nights Live at 7:00.
