SPARTA, Ky. (AP) -- Rain Saturday night forced NASCAR officials to postpone the Sprint Cup race at Kentucky Speedway until Sunday.
The 400-mile event was rescheduled for Sunday at noon.
Dale Earnhardt Jr. will start on the pole in a Chevy alongside Carl Edwards' Ford.
It was the circuit's first postponement since last year's season-opening Daytona 500. The marquee event ran the following night for the first time in its history.
Sunday's rescheduling creates the first day Cup race for the 1.5-mile oval after two events at night.
Showers were forecast all day around the state, which arrived around mid-afternoon with a heavy downpour followed by sporadic rain. NASCAR delayed the start and held out hope for a late start with jet driers on the track, but another band of rain led officials to postpone the race just after 9 p.m.
