Michael Annett died on December 5, 2025 at just 39 years old, shocking the NASCAR community. JR Motorsports confirmed his passing without releasing a cause of death, but Brad Keselowski’s tribute suggested Annett endured something far more serious than fans realized during his final years.
All About Brad Keselowski’s Tribute on X
Keselowski posted on X with a photo from their early ARCA days together, writing, “I remember this day vividly. Michael was an up and comer at the same time I was and he was looking really good. In the end, Life took us different paths and all of us who knew him and the talent he had are sad to see him go, but glad he is no longer suffering.”
That final line stopped everyone. “Glad he is no longer suffering” implied Annett battled something privately that the racing world never knew about. No official medical information has been disclosed, leaving fans and media searching for answers about what Keselowski meant.
Michael Annett’s Quiet Retirement Also Raises Questions
Annett retired from full time competition in 2021 after five seasons with Dale Earnhardt Jr.’s JR Motorsports. The official reason given was a stress fracture in his right femur that forced him to miss races. He never returned to competitive driving after that injury, transitioning instead to team ownership with Annett Enterprises where he mentored young drivers.
Looking back, some wonder if that stress fracture explanation masked a more serious diagnosis. Annett spent 2017 through 2021 as a steady presence driving the No. 1 Chevrolet for JRM, making 158 Xfinity Series starts and earning his biggest career victory at the 2019 Daytona season opener. His retirement at 35 years old seemed premature for someone still competitive, especially since he never publicly discussed ongoing health problems beyond the femur injury.
