It may be fitting that the last car Kasey Kahne ever drove in NASCAR Cup Series competition sported a throwback paint scheme to the red and white Evernham Motorsports car that made him famous.

Kahne has not competed in a Monster Energy NASCAR Cup Series race since Darlington Raceway’s annual throwback event on September 2nd, a race in which he suffered a severe dehydration which required medical attention.

On Tuesday, Kahne announced on Twitter that he would not compete in the remaining races of his final season because he was not medically cleared to after a private test at Charlotte Motor Speedway last week.

“It was my hope that everything would go well and I would be able to finish out the season strong in the #95 for Levine Family Racing. Unfortunately, that’s not the case,” Kahne wrote.

“Outside of the race car I am perfectly healthy, I feel great, and the doctors have determined that I have no underlying health problems. My body just can’t handle extended periods of time in the race car and we weren’t able to control the sweat ratio to keep my body hydrated enough to prevent any permanent damage to my body.”

In August, Kahne announced that he would retire from NASCAR at the end of the 2018 season, citing his dehydration issues as one of the factors that played in the decision to step away from Cup Series competition after the conclusion of his 2018 campaign.

In 529 Cup Series starts, Kahne complied 18 victories, including the 2017 Brickyard 400 and the Coca-Cola 600 in 2006, ‘08 and ‘12. He also was the Cup Series rookie of the year in 2004.

Though done with NASCAR, Kahne wrote that he intended to continue to compete in sprint car races, which are much shorter.

“See you all soon at the dirt tracks, and thank you for sticking with me over the years,” Kahne wrote.

Regan Smith will once again pilot the #95 Chevrolet for Levine Family Racing Chevrolet at this Sunday’s 500 at Talladega SuperSpeedway.
