NASCAR said Thursday that two-time Cup Series champion Kyle Busch has died at the age of 41. Busch was in his 22nd full-time season in NASCAR and won 63 races in the Cup Series. Busch's family said earlier in the day that he had been hospitalized for an unspecified severe illness.
We are saddened and heartbroken to share the news of the passing of Kyle Busch, a two-time Cup champion and one of our sport's greatest and fiercest drivers. He was 41 years old.

Busch is survived by his wife, Samantha, and their two children, Brexton and Lennix.
Busch joined NASCAR’s national ranks in 2001, debuting with RFK Racing, then known as Roush Racing, in the NASCAR Craftsman Truck Series. Before Busch reached NASCAR’s top levels, his older brother, Kurt Busch, had already established himself in the sport. The brothers made history in 2005 when they competed together full-time in the NASCAR Cup Series.

Hours before his death, Busch's family said he was in a hospital.
“Kyle has experienced a severe illness resulting in hospitalization. He is currently undergoing treatment and will not compete in any of his scheduled activities this weekend at Charlotte Motor Speedway. We ask for understanding and privacy as our family navigates this situation," they wrote.
Over a career spanning more than two decades, Busch drove for Hendrick Motorsports, Joe Gibbs Racing and Richard Childress Racing. Across NASCAR’s three national series, he earned 234 victories, the most all-time.
Busch had been scheduled to compete for Spire Motorsports in this weekend’s NASCAR Craftsman Truck Series race at Charlotte Motor Speedway in the No. 7 truck. Last weekend at Dover Motor Speedway, Busch captured his 69th Truck Series victory, which now stands as the final win of his career.
Absolutely cannot comprehend this news. We just need to think of his family during this time. We love you KB. https://t.co/cpaXg2HZGF

When Kyle climbed behind the wheel, he brought an intensity and determination that demanded respect from his competitors and inspired fans throughout motorsports," Smith said.
