Well there it is.
The family of NASCAR legend Kyle Busch released a statement today revealing what led to the sudden and shocking death of the 41-year-old on Thursday.
Just two weeks ago at Watkins Glen, Busch had said he was battling a sinus infection and asked for a doctor to meet him at his bus after the race to give him a shot. And last week at Dover, he said he was still dealing with the effects of what he called a “substantial cough” at Watkins Glen.
According to a statement just released by his family though, it sounds like it was actually more severe than even Busch realized.
The family revealed that, according to the medical examiner, Busch had developed severe pneumonia which had progressed into sepsis:
“The medical evaluation provided to the Busch Family concluded that severe pneumonia progressed into sepsis, resulting in rapid and overwhelming associated complications. The Family asks for continued understanding and privacy during this difficult time.”

Absolutely tragic, and an important reminder to take care of your health even when you think it’s nothing serious. (That’s a reminder that I need myself a lot of the time).
It was reported on Thursday morning that Busch had been hospitalized for a “severe illness” and would miss this weekend’s Coca-Cola 600 at Charlotte Motor Speedway, before it was announced that he had passed away a few hours later.
The AP reported on Thursday evening that Busch had collapsed while in the racing simulator at Chevrolet’s technical center just outside of Charlotte, North Carolina the day before, and dispatch reports show that the 911 call was made for someone experiencing shortness of breath around 5:30 PM.
And yesterday, TMZ obtained the audio of that 911 call, which revealed more about the emergency that led to his hospitalization.
During the call, the unnamed caller tells the dispatcher that Busch was still awake and alert at the time and was on the bathroom floor:
“I’ve got an individual that – shortness of breath, very hot, thinks he’s going to pass out, and is producing a little bit of blood, coughing up some blood.”
The caller also tried to keep emergency personnel from drawing too much attention to the scene:
“When you come in, if you could not make it – could you turn the sirens off when you get here?”

How quickly things can escalate…scary.
Meanwhile at Charlotte for the Coca-Cola 600, it’s a somber mood inside the rainy garage area, which seems fitting on a weekend like this.
Yesterday, RCR announced that they would be suspending their use of Busch’s #8 for the foreseeable future, and would renumber his car to the #33:
“Richard Childress Racing has elected to suspend use of the No. 8 and will run the No. 33 at Charlotte Motor Speedway and beyond. Kyle Busch was instrumental in the design of RCR’s stylized No. 8 and it has become synonymous with Kyle and an important symbol for his fans and the NASCAR industry. No one can carry it forward to the level that he did. The No. 8 is reserved and ready for Brexton Busch when he is ready to go NASCAR racing.”
Prior to the garages opening for Cup Series teams, NASCAR announced that it would allow RCR and the newly-renumbered #33 car to be the first to unload from their hauler this morning. And when it came time to pull the car off the trailer, the entire Cup Series garage gathered around in silence as Busch’s car was rolled out:
NASCAR President Steve O’Donnell addressed the media yesterday afternoon to share his thoughts on Busch, and reflected on the legacy that he’s leaving behind:
“Kyle Busch to me is an American badass. Behind the wheel, who you want to be. I think when you look back at all those things, that’s part of being a race car driver.”
He also confirmed that NASCAR would potentially be looking to add Busch to the NASCAR Hall of Fame immediately, alongside the class that was just announced for 2027. At the time of his death, Kyle Busch was the winningest driver in NASCAR history, with 63 Cup Series wins, 102 O’Reilly Auto Parts Series wins, and 69 Truck Series wins. He ranks 9th all time for Cup Series wins, including championships in 2015 and 2019.
His final victory came less than a week before his death, in the NASCAR Craftsman Truck Series race at Dover, when he dominated the race in typical Kyle Busch fashion before celebrating with his signature bow.
“Always one of my favorite places to race.”

Following his death, a joint statement was released from his family, NASCAR, and his Richard Childress Racing team:
“Our entire NASCAR family is heartbroken by the loss of Kyle Busch. A future Hall of Famer, Kyle was a rare talent, one who comes along once in a generation. He was fierce, he was passionate, he was immensely skilled and he cared deeply about the sport and fans.
Throughout a career that spanned more than two decades, Kyle set records in national series wins, won championships at NASCAR’s highest level and fostered the next generation of drivers as an owner in the Truck Series. His sharp wit and competitive spirit sparked a deep emotional connection with race fans of every age, creating the proud and loyal ‘Rowdy Nation.’
Our thoughts are with Samantha, Brexton and Lennix, Kyle and Samantha’s parents, Kurt and all of Kyle’s family, Richard and Judy Childress, everyone at Richard Childress Racing, his teammates, friends and fans. NASCAR lost a giant of the sport today, far too soon.”
