NASCAR driver Kyle Busch is hospitalized with a “severe illness” and will miss this weekend’s Coca-Cola 600 at Charlotte Motor Speedway, multiple outlets report. Busch, 41, is a two-time NASCAR Cup Series champion. According to statements attributed to his family, he is undergoing medical treatment and is not expected to participate in any activity connected to the event. Fox News and other reports note that the illness is not further specified, and the family asks for privacy during his recovery. The New York Post and other outlets also report that Busch will be replaced in his No. 21 car by Austin Hill for the Coca-Cola 600. Separate reporting indicates Busch was scheduled for additional racing activity around the weekend, including involvement in the NASCAR Craftsman Truck Series, though the extent of cancellations beyond the Cup race is described only generally. The Independent adds that Busch’s absence marks his first Cup Series race missed in more than a decade. No outlet provides further medical details beyond the family’s characterization of his condition as severe.
