Fans continue to mourn Kyle Busch two days after the NASCAR legend’s sudden and shocking death at age 41.
The two-time NASCAR Cup Series champion was hospitalized in Charlotte, North Carolina, earlier this week with what his family and the auto racing series termed a “severe illness.”

Busch was scheduled to compete in two NASCAR races at Charlotte Motor Speedway over Memorial Day weekend: a Craftsman Truck Series race that was reschedued for the morning of Saturday, May 23, and the annual Coca-Cola 600, the Cup Series’ longest race of the season on Sunday, May 24.
Busch won 63 Cup Series races, which ranks ninth on the all-time list, and season championships in 2015 and 2019. He holds the record for most wins in the second-tier O’Reilly Auto Parts Series with 102 and the Truck Series with 69. His most recent Trucks win came last weekend at Dover Motor Speedway, and his post-race interview has now taken on a whole new layer.

“I’ve got an individual that’s (experiencing) shortness of breath, very hot and thinks he’s going to pass out, and he’s producing a little bit of blood, coughing up some blood,” the caller told the dispatcher.
The caller identified the location as the General Motors Charlotte Technical Center off Speedway Boulevard in Concord, describing it as being next to Hendrick Motorsports. — Scooby Axson and Kristie Ackert
What illness did Kyle Busch die from?
Kyle Busch had a “severe illness,” according to a joint statement between his family and NASCAR, though no details were given. At the NASCAR Cup Series race May 10 at Watkins Glen, FOX Sports noted during its broadcast that Busch had been fighting a sinus cold. He radioed in to his team to have the track doctor meet him after that race, but he did not elaborate why. Less than a week later as NASCAR traveled to Dover, Delaware, for its All-Star Race weekend, Busch said he still wasn’t feeling great and “the cough was pretty substantial.”
