The on-again, off-again Boyd Gaming 300 NASCAR Xfinity race at Las Vegas Motor Speedway is off again — until Sunday.
The race will be finished approximately one hour after the conclusion of the Pennzoil 400 Cup Series race.
Overcast skies opened for the third time after Chase Briscoe won the first 45-lap stage. NASCAR made the announcement to postpone the race at 6:45 p.m., almost six hours after the scheduled 1 p.m. start.
