Officials found that the No. 13 truck was in violation of Section 20.4.17.d in the NASCAR Rule Book, which concerns the dimensions of a return flange at truck bed sides. As a result, crew chief Joe Shear Jr. was ejected and the team was docked 10 points in both the driver and team owner points standings.

Truck chief Rich Lushes was listed as the No. 13 team’s interim crew chief on the updated entry list and team rosters for Friday’s Henry Ford Health System 200 (6 p.m. ET, FS1, MRN, SiriusXM). Johnny Sauter is scheduled to start 13th in the No. 13 Ford.
