The World of Outlaws is ramping up its COVID-19 protocols following an outbreak after last weekend's event in Knoxville, Iowa.
The sprint car series confirmed "several drivers and crew members have tested positive for COVID-19" following the Saturday night main event won by suspended NASCAR driver Kyle Larson.
Daryn Pittman, Tori Knutson and Paul McMahan all confirmed they had tested positive for the coronavirus. Kraig Kinser Racing and Roth Motorsports said team members had tested positive, and Knoxville Raceway said one of its employees had tested positive.
Series officials urged anyone at the track who had come into contact with those infected to get tested.
