Heavy rains have returned to Bristol Motor Speedway, bringing out the second red flag of the night and making the possibility of postponent of the Bass Pro Shops NRA Night Race a very real possibility.
The 40-car field logged a total of 48 laps -- 38 before the first rainstorm hit, then 10 more under caution before a second deluge arrived.
The start of the race also was delayed approximately 30 minutes because of inclement inclement weather.

At 9:54 p.m. ET, the rain had finally stopped -- and NASCAR began attempting to dry the track at 10:03 p.m. Cars took to the track shortly thereafter, but ran only 10 laps under caution before more rains, heavier this time, hit the 0.533-mile short track.
Earlier, the BMS grandstands were cleared twice by track officials because of rain and lightning in the area.
The second call to clear the stands came shortly before the scheduled dropping of the green flag and delayed the start of the race by approximately half an hour.
Even though the short track does not take long to dry, the forecast for the remainder of the night and is spotty at best for Sunday.
According to an adjusted Weather.com forecast, the chances of precipitation for the remainder of the night were much worse than the website had been predicting earlier in the evening. Chances of precipitation jump back up to 45 percent at midnight, and go to 50 percent at 1 a.m.
Kyle Busch was leading the race when the rains hit.
