Weather cancels final Sprint Cup practice, postpones XFINITY race

RELATED: Live weather updatesWeekend schedule

After spotty rain affected events all day Saturday at Dover, NASCAR postponed the XFINITY Series' Drive Sober 200 until 10 a.m. ET Sunday (CNBC, MRN, SIRIUS XM).

The second race of the NASCAR XFINITY Series Chase was set to be the capstone to a day of action at Dover International Speedway.

Fans with tickets to either race will be admitted for both. Tickets are available here

Chase for the NASCAR Sprint Cup drivers Kyle Busch, Joey Logano and Austin Dillon all were entered in both races and faced the prospect of 600 high-speed laps at the Monster Mile in a single day Sunday with the schedule change.

Thus, Ryan Blaney now is scheduled to wheel the Team Penske entry for Logano,  Regan Smith will replace Dillon and Drew Herring will drive for Busch. 

Saturday's on-track action started well for the second Sprint Cup practice at Dover. But sprinkles turned to heavier rain with 15 minutes left in that practice, bringing out the red flag after 45 minutes of the 55-minute session.

XFINITY Series qualifying was also off to a good start, but was scrapped after just one round, handing Erik Jones the pole position.

Final Sprint Cup practice was set for 1:30 p.m. ET, but ultimately was canceled due to inclement weather. 

Friday's Sprint Cup Coors Light qualifying also was canceled due to persistent rain. The field was set by owner standings, allowing Brad Keselowski to start P1 for the second time this year. The Sprint Cup Series will return to the track tomorrow for the Citizen Soldier 400 at 2 p.m. ET (NBCSN/NBC Sports App).
