Trevor Bayne has been diagnosed with multiple sclerosis but will continue to race in NASCAR.
The Roush Fenway Racing driver was cleared by doctors and NASCAR after extensive testing at the Mayo Clinic, according to a team release Tuesday.
"I've never been more driven to compete," Bayne said in a release. "My goals are the same as they've been since I started racing. I want to compete at the highest level and I want to win races and championships. I am in the best shape I've ever been in, and I feel good. There are currently no symptoms, and I'm committed to continuing to take the best care of my body as possible."
Bayne, 22, became an overnight sensation in 2011 when he became the youngest winner of the Daytona 500, triumphing with the fabled Wood Brothers Racing team in only his second start in NASCAR's premier series. In April he was sidelined for two months after complaining of numbness in his arm during a race at Texas Motor Speedway. Bayne, who also battled symptoms of blurred vision, nausea and fatigue, said he was diagnosed with Lyme Disease at the Mayo Clinic in Minnesota.
He has driven full time in the Nationwide Series this season and is ranked sixth in the standings with a victory at Iowa Speedway. He has continued to race part time in Cup with Wood Brothers Racing, posting three top 10 starts in 45 starts from 2010-13.
The Knoxville, Tenn., native won't be the first driver to race with MS in a NASCAR national series. Kelly Sutton, who was diagnosed with MS as a teenager, made 54 starts in the Camping World Truck Series from 2003-07.
Bayne will drive full-time in the No. 6 Ford Mustang during the 2014 Nationwide Series season.
"We are 100 percent supportive of Trevor and his ability to compete in a race car," Roush Fenway team owner Jack Roush said in the release. "I have full confidence in Trevor and his partners have all expressed that same confidence and support. As with all of our drivers, we look forward to standing behind Trevor and providing him with all of the tools he needs as he continues to develop in his young career."
