Tyler Reddick’s 23XI Racing team was penalized Saturday afternoon at Charlotte Motor Speedway and it will carry over into the start of Sunday’s Coca-Cola 600.
The No. 45 Toyota Camry XSE passed inspection and then the team made an unapproved adjustment to the underwing. Reddick will be allowed to practice and qualify but will drop to the rear of the 39-car field for the start of the race on Sunday evening. After the green flag, Reddick will also have to serve a pass-through penalty.
Billy Scott and his team also lost their pit stall selection for the race. Michael Hobson, the team’s car chief, was ejected for the remainder of the weekend.
Reddick has finished ninth or better in all four of his Coca-Cola 600 starts. A fifth-place finish in last year’s event was a career best.
