Severe storms capable of damaging winds, large hail and possible tornadoes forced the Roto-Rooter Midweek Series race scheduled for Tuesday at Arrowhead Speedway in Colcord, Oklahoma, to be postponed. Arrowhead and the series are seeking a makeup date, and patrons with pre-purchased tickets will be accommodated or may request refunds through the speedway.

High Limit Racing will instead race at the Texas Motor Speedway dirt track on April 30 and May 2 as part of the Drydene Stockyard Stampede powered by Reladyne. The Stockyard Stampede field includes defending winner Rico Abreu and two-time Texas winner Brent Marks, plus NASCAR entrants Kyle Larson and Corey Day. Larson is slated to contest all three High Limit events in the Silva Motorsports No. 57 and had been set to make his first appearance at Arrowhead. Corey Day, aligned with Hendrick, will drive the Jason Meyers Racing No. 14 at Texas and recently won a NASCAR O’Reilly Auto Parts Series race.

The postponement affects this week’s Midweek Series schedule and championship points. Tanner Thorson and Rod Gross Motorsports entered the week as the points leader. Aaron Reutzel (54 points back), Giovanni Scelzi (59 back), Rico Abreu (61 back) and Tyler Courtney (80 back) trailed with 52 nights remaining in the title fight. Ryan Timms and Liebig Motorsports top the Midweek Series standings after two of 16 rounds, but Timms will not contest the Arrowhead date, effectively leaving Thorson and Courtney as the de facto midweek points leaders for that event. The Midweek Series title carries a $25,000-to-win prize.

Several drivers were set to debut at Arrowhead before the postponement, including Aaron Reutzel, Brent Marks, Justin Peck, Daison Pursley, Sye Lynch, Chase Randall and Brenham Crouch. Giovanni Scelzi, Rico Abreu, Tyler Courtney and Tanner Thorson have previously run laps at Arrowhead. Series organizers also noted support-side changes: new crew chief Michael Dutcher has overseen stronger results for Hank Davis, who finished 7th at Route 66, 5th at Lucas Oil and 7th at Eagle. The next scheduled Midweek stop is Tuesday, May 19 at Grandview Speedway in Bechtelsville, Pennsylvania, which will be simulcast on FS1 and FloSports, and the Stockyard Stampede will serve as a tune-up ahead of the All-In Championship Weekend on Oct. 16–17.
