Inclement weather cancels Friday's track activity at Indianapolis Motor Speedway. NASCAR fans will have to wait until Saturday for racing action.

DOVER − The NASCAR Cup Series race at AutoTrader EchoPark Automotive 400 at Dover Motor Speedway was delayed by rain with 14 laps remaining on July 20. The delay lasted 56 minutes as a storm moved quickly through the area. NASCAR officials set a drop-dead time of 8:10 p.m. because Dover doesn't have lights at the racetrack.

The rain has shown up once again at Dover Motor Speedway and put the NASCAR Cup Series race on hold for the time being. We have not gone to a red flag at the moment, but could see a stoppage if the rain picks up.

The AutoTrader EchoPark Automotive 400 was delayed by a fast-moving storm cell on Sunday, but the rain cleared out of Dover just as soon as it started up. It was heavy enough, however, to soak the track, so the race had to enter an extended delay while the track dried.

Denny Hamlin collected his second straight win at Dover Motor Speedway on Sunday, but the broadcast audience for the NASCAR Cup Series race took a hit during a late rain delay.
