The 43-year-old Gordon is coming off one of his best seasons in years. He won four times in 2014, including the Brickyard 400.
He says he's not officially calling it a retirement because there is "always the possibility I'll compete in selected events, although I currently have no plans to do that."
12/15/14 Jeff Gordon Q&A with Ryan McGee on ESPN.com:
McGee: "This was your best finish in seven years. Under the old Chase system, you'd have finally won a fifth title. But we writers still come at you with retirement questions. So … retirement?"
Gordon: "I don't believe in retirement, No. 1, but I know that I won't always be a full-time Cup driver. That time is coming. Remember in May, my back got so bad I couldn't get out of bed, let alone into a race car? So will that play a role in retirement sooner rather than later? It's very possible. It seems to be the one limiting factor that I have right now. But there's no plan. There's no countdown. I'm racing." see full Q&A at ESPN.com
