Riley Herbst will not compete in the NASCAR Cup Series regular-season finale at Daytona International Speedway on Saturday night. The 23XI Racing driver is withdrawing because of “lingering effects” from an incident that occurred last weekend, the team says.

Herbst qualified fifth for the race on Friday, but his absence requires a driver change. According to the team statement, Herbst woke up with lingering effects and, with his team, decides it is in his best interest to step out of the car for Saturday’s Daytona event. With Herbst out, Burton will start at the back of the field.

Outlets report the same core development: 23XI Racing makes the announcement hours before the green flag and cites lingering physical effects from the prior crash as the reason for Herbst’s withdrawal. Differences are limited to wording and timing details rather than the underlying facts.
