Bayne was launched into the national spotlight in 2011 when he became the youngest driver ever to win the Daytona 500. He was 20 at the time and driving a partial Sprint Cup schedule.
Now 22, he says he will compete at Homestead-Miami Speedway this weekend in the season finales for both the Nationwide and Sprint Cup series. He has one Nationwide win this season, at Iowa, and is ranked No. 6 in the points standings of that series.
Bayne also said he still expects to compete full-time for Roush-Fenway Racing in the Nationwide Series, as well as a partial Sprint Cup schedule for The Wood Brothers as planned next season.
His younger sister, Sarah, also has multiple sclerosis, a disease in which the immune system attacks the central nervous system.
Bayne was hospitalized and missed five races in 2011 for an illness doctors called an "inflammatory condition."
