What was supposed to be the season opener for the Knoxville Raceway with the World of Outlaws Nos Energy Drink Sprint Cars, turned into a rain out. Persistent drizzle forced officials to call off the night on Friday; it would not have dried out until well after eight. This weekend now becomes a one day show for the Knoxville Raceway as many of the same 63 cars that signed in Friday will run tonight. KNIA will have complete coverage with Live Track Side at 5:00 and Race Nights Live at 7:00.
