Kurt Busch, 44, has missed ten races now as he continues his recovery. In his absence, Ty Gibbs has been brought in as a substitute driver at 23XI Racing.
Although he withdrew his medical waiver, thus forfeiting his position in the playoffs, the No. 45 Toyota remains in the owner's championship hunt. As a result, the team swapped car numbers and put Bubba Wallace in the No. 45 car.
