RFK Racing has announced that No. 17 driver Chris Buescher has tested positive for COVID-19 and will miss this weekend’s NASCAR Cup Series event at World Wide Technology Raceway (formerly Gateway Raceway). NASCAR Truck Series front runner Zane Smith will fill in for Buescher, piloting the No. 17 Acronis Ford as NASCAR makes its much-anticipated return to WWTR. This marks the NASCAR Cup Series debut for Smith, a two-time NASCAR Truck Series Championship runner-up.

Smith has three wins and eight top-10 finishes in 10 starts in the Truck Series this season, having led 253 laps while piloting the No. 38 Ford F-150. He will become the 24th driver to pilot an RFK Ford for Jack Roush in the NASCAR Cup Series.

Buescher expects to return to action next week at Sonoma.
