McMurray overcame the two-hour pothole delay and Dale Earnhardt Jr. in the final lap of a double-overtime sprint finish to win his first Daytona 500.
McMurray said Tuesday during a stop in New York that he thought it was a piece of rubber causing the delay, noting the track was shaded at that spot. The 36-year-old from Joplin, Mo., brushed off the two delays Sunday, using the down time to talk to his crew chief.
In a wild finish, McMurray outlasted 12-time Daytona winner Earnhardt.
McMurray made the talk show rounds before heading to Los Angeles for the Auto Club 500 on Sunday.
