After Friday’s practice, NASCAR confiscated the hood louvers from the cars of Larson and his Hendrick Motorsports teammates, William Byron, Alex Bowman and Josh Berry (subbing for injured Chase Elliott).

NASCAR is taking the single-source parts to its research-and-development center in Concord, N.C., for further evaluation. If any penalties are forthcoming, they will be announced next week.

As of Saturday morning, the hood louvers on all four cars had been replaced. On Saturday before qualifying NASCAR took the louvers from the No. 31 Kaulig Racing Chevy of driver Justin Haley who qualified 26th.

Just like the Hendrick cars on Friday, any penalties will be announced next week.
