Green-white-checkered flag rule changes; Danica Patrick’s practice smooth; Jimmie Johnson in wreck

DAYTONA BEACH, Fla. — UNDER REVIEW: NASCAR officials are considering a change to their policy on making only one attempt at a so-called "green-white-checkered" finish to races that would otherwise finish under caution.

Under the current policy, officials will add two green-flag laps to the end of the race to avoid a finish under yellow in the event of a late-race accident - but they'll only try it once.

But after Saturday night's Bud Shootout ended under caution because of an accident during NASCAR's version of overtime, officials could change the policy to make multiple attempts at a finish under green.
