An afternoon rainstorm was too much to overcome at the Knoxville Raceway and officials called off the night just before 4:00 on Saturday afternoon. This is the first rainout of a weekly show this season as the only other rainout was the season opening World of Outlaws race in April. Next week is the Marion County Fair race. Live coverage is on KNIA with Live Track Side at 5:00 and Race Nights Live at 7:00,.
