A Midwestern Return for NASCAR's O'Reilly Series
The NASCAR O'Reilly Series is set to make its long‑awaited return to Chicagoland Speedway this July, reviving the historic Cuervo 300 after a two‑year hiatus forced by the COVID‑19 pandemic.
Series officials have confirmed a full slate of 38 entries, guaranteeing that every registered driver will take the green flag, a rarity that underscores the event’s growing appeal.
Notable drivers and teams
Among the confirmed competitors are rising stars Connor Zilisch and veteran Chase Elliott, both fielded by JR Motorsports, while Nick Sanchez will once again pilot the No. 87 entry for Peterson Racing Group.
The weekend will also feature an off‑weekend for the NASCAR Truck Series, allowing teams to focus on the unique challenges of the 1.5‑mile Illinois oval, where the blend of high‑speed drafts and tight corners promises competitive racing.
