CONCORD, N.C. (AP) — Two-time NASCAR Cup Series champion Kyle Busch has been hospitalized with a severe illness and won’t compete at Charlotte Motor Speedway this weekend, his family said Thursday.

His family posted the news on social media and said he is currently undergoing treatment.

“We ask for understanding and privacy as our family navigates this situation,” the statement continued.

During a Cup Series race on May 10 at Watkins Glen, Busch radioed in to his crew requesting medical aid from Dr. Bill Heisel and a “shot” after the race. According to the TV broadcast, Busch had been struggling with a sinus cold that was exacerbated by the intense G-forces and elevation changes at the Upstate New York road course.

Busch continued to race and finished eighth. Busch ranks 24th in the Cup Series standings, with two top-10 finishes in 12 races this season. The 41-year-old driver and Las Vegas native won championships in 2015 and 2019. Busch is in his fourth season at Richard Childress Racing after winning titles with Joe Gibbs Racing.

His last win came in 2023, his first with RCR. One of NASCAR’s most polarizing personalities, Busch has won 234 races across the sport’s three national series, more than any driver in history.
