23XI Racing's Tyler Reddick initially qualified 12th for Sunday afternoon's FireKeepers Casino 400 at Michigan International Speedway, a race he won last yearin August en route to claiming his first NASCAR Cup Series regular season title. But he will not actually get to start there.
As a result of the fact that the No. 45 team have changed the splitter extensions on the No. 45 Toyota after an issue in practice on Saturday, Reddick is set to drop to the rear of the field.
He is now set to start this 200-lap race around the four-turn, 2.0-mile (3.219-kilometer) Brooklyn, Michigan in 36th (last) place, at the tail end of the outside lane.
Because of how "to the rear" penalties work in NASCAR, only the drivers who had been slated to line up behind Reddick on the outside lane are set to move up, each by one row. The drivers on the inside lane are unaffected.
For example, Team Penske's Ryan Blaney qualified 13th, and he is still set to start there, while Spire Motorsports' Carson Hocevar, who qualified 14th, is now set to move up to the sixth row and start 12th as a result of Reddick's penalty.
