Posted by Sabrina B. @gametimegirl NASCAR postponed the Daytona 500 because of rain, the first time in the 54-year history of the event that it has been delayed.  The 500-mile race was rescheduled for noon today & will be aired on Fox. WWE star John Cena will still wave the honorary green starter flag at the Daytona 500  — despite rumors the wrestling star would be forced to miss the race.
