Graham Rahal faces a 10-spot grid penalty for the Detroit Grand Prix on Belle Isle on Sunday.
Rahal, who drives the No. 38 car, had to change a blown engine during preparation for the Indianapolis 500 that was run May 27.
Rather than penalize the driver for the famed race at the Brickyard, IndyCar said penalties would carry over to the Detroit street-course race.
Rahal will be placed back 10 spots from wherever he qualifies Saturday, so 11th would be the best starting position he could have for the 90-lap race.
Rahal, who is 14th in driver points, is also on IndyCar probation because of an incident with fellow driver Marco Andretti during the race at Long Beach, Calif.
Rahal drives for Target Chip Ganassi Racing, the team that includes Indy 500 winner Dario Franchitti.
