Michael Annett — who last entered a major NASCAR series race in 2021 and enjoyed his best seasons as part of JR Motorsports — has passed away, according to RSMG, a brand marketing agency representing the former Cup and Xfinity Series driver’s longtime primary sponsor Pilot Flying J.
No cause of death was immediately given for Annett, who was 39.
Our condolences go out to the family of Annett, a Des Moines, Iowa native who had flown under the radar for several years since making his final NASCAR national series start at Phoenix Raceway in the 2021 Xfinity Series finale.
We are sad to have lost a family member. Michael Annett will always be in our hearts. Our thoughts are with the Annett family at this time.
Rest in peace MA. pic.twitter.com/nr91CeTwis

Looking Back On The NASCAR Career Of Michael Annett
Michael Annett’s career in NASCAR’s big leagues began in 2008 and continued over at least part of 14 consecutive seasons.
All told, Annett made 436 starts across NASCAR’s Cup, Xfinity and Truck divisions but spent the overwhelming majority of his time in the Xfinity Series, where he competed in 321 races.
Annett recorded one NASCAR national series victory, which came in the 2019 Xfinity Series opener at Daytona International Speedway. He finished a career-best fifth in the Xfinity standings in 2012 and placed ninth in final Xfinity points on four occasions.
Despite never being a consistent frontrunner, Annett recorded 95 top-10 finishes — including 19 top-fives — over 10 seasons as a full-time Xfinity Series driver.
During his final season of 2021, Annett missed seven races and underwent surgery to repair a stress fracture in his right femur.
After competing full time in the Xfinity Series from 2009-2013, Annett spent three seasons as a full-time driver in the NASCAR Cup Series. He led a total of 13 laps in NASCAR’s premier division, earning a best points finish of 33rd.
JR Motorsports, Brad Keselowski, Others Remember Michael Annett
Michael Annett returned to the Xfinity Series full time in 2017, joining Dale Earnhardt Jr. co-owned JR Motorsports (JRM). And that’s where he finished out his career in 2021, after running every Xfinity Series race for JRM from 2017-2020 and securing his lone major NASCAR victory along the way.
Annett shouted out JRM in a letter, which you can read below, that he penned at the end of his last season. The letter also highlighted other teams he competed for, including Richard Petty Motorsports, Bill Davis Racing, Germain Racing and Rusty Wallace Racing.

Late Friday, JRM mourned the loss of Annett, who registered three ninth-place points finishes over his four full seasons with the company. In a post on X, which you can read in full below, the organization called Annett “a key member of JRM from 2017 until he retired in 2021.”
Our thoughts and prayers are with the entire Annett family with the passing of our friend Michael Annett. Michael was a key member of JRM from 2017 until he retired in 2021 and was an important part in turning us into the four-car organization we remain today. https://t.co/oZdMymjBz6 pic.twitter.com/PUsCZHkXEg

Meanwhile, others within the NASCAR world also used the social media platform to share tributes and express condolences to those most impacted by the death of Annett, who would have turned 40 on June 23 of next year.
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. #RipMichael https://t.co/2imAJrMFM9
