The NTT IndyCar Series postpones the Borchetta Bourbon Music City Grand Prix at Nashville Superspeedway due to inclement weather. Both reports say the race, originally scheduled for Sunday, is moved to Monday at 3:00 p.m. ET. One outlet notes that weather impacts the event throughout the afternoon, indicating conditions worsen as the day progresses. The other report also attributes the delay to inclement weather and confirms the updated start time. No additional changes or cancellations are reported in the provided accounts. The series and Nashville Superspeedway therefore proceed with the revised schedule, with teams and drivers preparing for Monday’s race start at the stated afternoon time. The postponement reflects weather conditions affecting the ability to hold the race as planned on Sunday.
