NASCAR driver Casey Mears reflected on the death of Kyle Busch on Friday, saying his impact on the sport of professional racing was "immeasurable."

Busch died at the age of 41, hours after it was announced he was going to forgo any racing activities at Charlotte Motor Speedway this weekend due to a "severe illness resulting in hospitalization."

Mears appeared on Fox News Channel’s "Fox & Friends First" as he mourned Busch’s death.

"I would say, really, it’s immeasurable. What he’s accomplished in the sport is done by nobody else. Kyle’s won so many races," he said of Busch’s impact on the sport. "I mean, there was a stretch there for a handful of years where if Kyle didn’t win a Busch race, a Cup race or one of the truck races throughout the weekend, something was wrong because he was constantly winning races.

"I think that the end of the day he was just a tremendous competitor you absolutely knew he was going to leave 110% on the table at all times. Just one of the best that’s ever been in a racecar. The biggest thing is that he’d just become such an amazing dad, father, husband, brother. I’m just thinking about everybody in the family. Tom and Gaye, his mom, and brother, obviously Samantha and the kids. He was a true champion at home as a family man as well."

NASCAR, the Busch family and Richard Childress Racing announced the death Thursday evening, but did not offer a cause of death.

"On behalf of the Busch family, everyone at Richard Childress Racing and all of NASCAR, we are devastated to announce the sudden and tragic passing of Kyle Busch," the statement said. "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.

KYLE BUSCH ON ‘HANG OUT WITH SEAN HANNITY'

"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.

"During this incredibly difficult time, we ask everyone to respect the family’s privacy and continue to keep them in your thoughts and prayers. Further updates will be shared as appropriate."

Busch was a two-time NASCAR Cup Series champion and had been on the series since 2004. He made 762 career starts with 63 wins. Busch won the championship in 2015 and 2019, and had 234 victories across all three NASCAR national series.

Busch is the all-time record-holder for wins in both the NASCAR O'Reilly Auto Parts Series (102) and NASCAR Craftsman Truck Series (69). His most recent win came last weekend at Dover, where he led 147 laps in a dominating Truck Series victory.
