DAYTONA BEACH, Fla. -- Austin Dillon will stand by as a possible relief driver for Kevin Harvick in Saturday night's Coke Zero 400, the NASCAR Wire Service has learned.
Harvick and his wife, DeLana Harvick, are expecting their first child, and there's a possibility the baby may be born Saturday, which also is DeLana Harvick's birthday.
"Happy birthday @DeLanaHarvick could be an interesting one," Harvick posted on his Twitter account just before noon ET on Saturday.
Dillon flew home to North Carolina after finishing fourth in Friday night's NASCAR Nationwide Series race, intending to race Late Models before heading for a Nationwide event at New Hampshire Motor Speedway, according to sources close to the situation.
But Dillon was returning to Daytona on Saturday in case his services were needed. Harvick said in his Thursday media availability at Daytona that he didn't have a back-up arranged, but apparently that changed as the weekend progressed.
