NASCAR has postponed the season-opening Daytona 500 until Monday because of two days of rain at Daytona International Speedway.
The race was scheduled to begin Sunday afternoon but amid heavy doubts that the green flag would wave on time, if at all. The final practice for the event was canceled Saturday, as was the Xfinity Series race.
The Xfinity Series race is now scheduled to be held Monday morning, hours ahead of the 4 p.m. start time for the Daytona 500.
