Ross Chastain had driven the No. 45 entry to an apparent third-place finish in the SpeedyCash.com 220 at the Fort Worth, Texas, track. But post-race technical inspection revealed a violation of Section 184.108.40.206.a in the NASCAR Rule Book, which states: “The throttle body must be used as supplied by the NT1 engine supplier without modification.”
As a result of the infraction, the Niece No. 45 was dropped to last place in the 36-truck field.
