Kyle Busch's older brother, Kurt Busch, has broken his silence, weeks after the NASCAR legend died at the age of 41.
The retired NASCAR driver, 47, released a heartfelt tribute honoring his baby brother, who died on Thursday, May 21, 2026, after suffering complications from severe pneumonia that progressed into sepsis, hours after he was hospitalized with a "severe illness."
"Thank you from the bottom of my heart. Thank you, everyone, for the well wishes, support, and love for my brother and our family," Kurt began in a statement on Instagram.
"Finding a silver lining, I reflect back on the days Kyle and I raced anything we could get our hands on. From big wheels to competing on the biggest stages in motorsports, we were more than just fierce competitors.
He continued: "We pushed each other, challenged each other, and learned from each other. Kyle, your passion, determination, and love for your family inspired everyone who knew you.
"No trophy, championship, or accomplishment could ever measure the impact you had on my life and on so many others. I will forever be grateful for the memories we made, the lessons you taught me, and the brotherhood we shared."
Kurt concluded: "My heart is broken, but I know your spirit will always ride with me. Rest easy, little brother."
The post was accompanied by photos of Kurt and Kyle over the years, as well as snaps of Kyle's family, wife Samantha Busch, and their two children: son Brexton, 11, and daughter Lennix, four.
