During Sunday's pre-race inspection, Logano's team was discovered to have driver gloves that did not meet SFI specifications.
The gloves were not only a safety violation but also a competitive issue, as the gloves were discovered to have been altered to provide a potential competitive advantage.
Allegedly, the team webbed his gloves between the thumb and index finger so he could place it against the holes in the window net, potentially to reduce drag during the full-throttle qualifying lap.
The issue falls under Section 14.3.1.1 of the NASCAR Cup Series rule book.
For Sunday's race, Logano - who qualified second for the race - will have to drop to the rear of the field and will have to serve a drive through penalty after he takes the green flag.
The team also faces potential serious NASCAR penalties for the competitive aspect of the violation, which will be announced next week.
During the Fox Sports broadcast of Cup qualifying on Saturday, Logano could be seen taking his left hand off his steering wheel and sliding it out the driver's side window net.
In addition, Cup driver Chase Elliott will have to start Sunday's race from the rear of the field due to unapproved adjustments.
The Atlanta race, the second round of the 2024 NASCAR Cup season following the rain-delayed Daytona 500 won by William Byron, gets under way at 8pm GMT (3pm local time).
