Wednesday night's UNOH 200 NASCAR Camping World Truck Series race at Bristol Motor Speedway has been postponed due to rain. 
 
The 200-lap event never got underway, as rain began to fall around the 0.533-mile speedway just after driver introductions concluded. 
 
With the postponement that came at 9:55 p.m. ET, NASCAR officials said the race would be run Thursday morning at 10 a.m. ET, airing live on FOX Sports 1 before the day's opening Nationwide Series practice at the track.

Once the race gets underway, Kyle Busch and Cole Custer will lead the field to the green flag, followed by Ron Hornaday Jr., Brad Keselowski, Gray Gaulding, German Quiroga, Michigan winner Johnny Sauter, Darrell Wallace Jr., Ben Rhodes, and Brandon Jones. 
 
The Kyle Busch Motorsports trucks set the pace in Wednesday's lone practice session, with Wallace Jr. leading Busch atop the leaderboard. Gaulding, Hornaday Jr., and Custer rounded out the top five.
