Steve Byrnes steps aside from NASCAR on FOX to focus on health

Steve Byrnes is a veteran of the NASCAR on FOX on-air team.

Longtime NASCAR on FOX on-air personality Steve Byrnes is taking an indefinite medical leave of absence, effectively immediately, to focus on his health after receiving news he has suffered a recurrence of cancer.

Byrnes, who was diagnosed and successfully treated for head-and-neck cancer in late 2013, steps away from his NASCAR Race Hub co-hosting and NASCAR Camping World Truck Series play-by-play duties for FOX Sports 1 to concentrate on his upcoming medical treatment and time with his family.

Any further updates on Byrnes will come at the discretion of the family.
