BRISTOL, Tenn. – Mother Nature won out for the second consecutive day Sunday at Bristol Motor Speedway, forcing the postponement of both the Food City Dirt Race and the Pinty’s Truck Race on Dirt.

NASCAR officials made the decision to cancel all scheduled on-track activity for Sunday at noon ET.

The move was based on a combination of factors, including additional strong storms that came through Northeast Tennessee Saturday night, a bleak Sunday forecast and safety concerns due to flash flood warnings in Sullivan County, where Bristol Motor Speedway is located.

In addition, the amount of rain at Bristol wreaked havoc with any potential attempts to get the Bristol dirt dry enough to be packed down and in raceable condition for either series.

The 150-lap NASCAR Camping World Truck Series feature, originally scheduled for 9 p.m. ET Sunday night, shifts back to noon ET Monday, with live coverage on FS1, MRN and SiriusXM, channel 90.

Meanwhile, the 250-lap NASCAR Cup Series main event is scheduled for a 4 p.m. ET start Monday afternoon, with live coverage on FOX, PRN and SiriusXM, channel 90.

All tickets for the Food City Dirt Race will be honored at the gate throughout the day Monday. Cup ticket holders that arrive early whose seats are occupied by a Truck race ticket holder can watch the Pinty’s Truck Race on Dirt from an open, socially-distanced seat.

Truck race ticket holders can use their tickets for their reserved seats during the Truck race and can also stay for the Cup event, but may need to relocate for the Cup race due to social distancing requirements.

Tickets will not be sold at the gate on Monday.

The Speedway Motorsports weather guarantee is in effect for ticket holders that cannot attend either race Monday.

When the action does go green on the .533-mile dirt surface at Bristol, John Hunter Nemechek and Austin Hill will start first and second for the Truck Series main event, while Denny Hamlin and Ryan Blaney will share the front row for the Cup Series feature.

Kyle Larson, the scheduled polesitter for the Cup Series race based on the metric formula and the washout of Saturday’s heat races, will drop to the rear of the field due to an engine change from Friday.

Monday will mark the first Cup Series race on dirt since 1970, when Richard Petty won by two laps over Neil Castles at the half-mile North Carolina State Fairgrounds in Raleigh, N.C.
