Earnhardt is calling it a career after Sunday’s NASCAR Cup race at Homestead-Miami Speedway. Earnhardt says he’s been touched by the well-wishes and video tributes in his honor. The 14-time winner of NASCAR’s most popular driver award says he’s healthy and hopes to finish the race on his terms.

“It would be a bit of a heartbreaker if we have the kind of issue that would take us out of an event and we couldn’t finish,” he said Friday.

Earnhardt is rooting for long-time friend Martin Truex Jr. to win the Cup championship Sunday. “I’m Team Martin this weekend, for sure,” Earnhardt said.

Earnhardt was also set to pose for team photos with friend Matt Kenseth, also on his way out of NASCAR. Kenseth has no ride lined up for 2018.
