The NASCAR O’Reilly Auto Parts Series is set to make its highly anticipated return to Dover Motor Speedway for the 2026 BetRivers 200, a 200‑mile event that will be televised on The CW at 4 p.m. Eastern on Saturday, May 16.
Dover is notorious among drivers for its steep banking, narrow groove and relentless tire wear, characteristics that turn every lap into a test of precision and nerve.
The official entry list features 39 cars, meaning that despite the large field, a single team will miss the showdown, adding an extra layer of strategy for the teams fighting for a spot.
Headlining the field is Ross Chastain, a playoff contender who will pilot the No. 9 Chevrolet for JR Motorsports in his fifth start of the season. He will be joined by Sheldon Creed, who returns to the No. 00 for Haas Factory Team, and Justin Allgaier, who continues his strong record at Dover in the No. 7 for JR Motorsports.
The roster also includes a mix of veteran talent such as Austin Hill, Sam Mayer, Jesse Love, Carson Kvapil, William Sawalich, Corey Day, Taylor Gray, Brent Crews, Harrison Burton, Brandon Jones, Ryan Sieg, Josh Bilicki, Garrett Smithley, Jeremy Clements and Rajah Caruth, each bringing distinct experience and recent performances that could reshape the playoff picture.
Playoff implications
With the season approaching its midpoint in a 33‑race schedule, a strong finish at Dover could provide crucial momentum for drivers eyeing a playoff push, while the track’s history of crashes and surprise finishes guarantees an unpredictable spectacle.
