NASCAR has postponed the remainder of the Xfinity race at Charlotte Motor Speedway on Monday until after the Cup Series race.
The Coca-Cola 600 is scheduled to begin at 3 p.m. ET. Last year's Coca-Cola 600 ran 5 hours and 13 minutes.
Persistent rain brought out the red flag on the Xfinity Alsco Uniforms 300 after 48 laps, with Ty Gibbs as the race leader. The caution flag came out after Lap 45.
The race was red-flagged a first time at Lap 25 after a mist dampened the track.
The Xfinity race was first postponed from Saturday due to rain and the Cup Series Coca-Cola 600 was postponed from Sunday night.
