In every amazing comeback story comes one person who never believed it could happen.

In Xfinity driver Matt Tifft’s case, that came in the form of one doctor who told him that a brain tumor, which he had removed in July, would be career-ending.

The 20-year-old didn’t listen and after returning to the track part-time in September, he will be given a spot with Joe Gibbs Racing full-time in 2017, the team will announce on Friday.

His return to the track has been chronicled by ProAthlete TV, and a mini documentary is coming soon. The spot with JGR is announced in a trailer for the project.

“It’s still an ongoing process,” he said of his health. “Even this last week I had to go get my 8-week check-up MRIs. It’s a never-ending thing and it will be that way for a long time and it’s a little reminder of everything that did happen. So going back to the racetrack and stuff is a nice way to make things feel normal again.”

As for the doctor who told him he wouldn’t race again? He said he’s glad he got a second opinion.

“I remember sitting there in July not knowing if I would be in a seat this year, next year or whatever so it was a little bit of a scary feeling there,” he said. “To be back this year and running well has been pretty incredible.”
