Dario Franchitti will start from the rear of the grid for Sunday's IndyCar race in Baltimore after being issued a 10-place penalty for an unapproved engine change.
The Scot, who had qualified 15th, was sanctioned after Honda was forced to replace his engine before it had reached the minimum threshold of 1850 miles as dictated by the regulations.
He will line up at the back alongside Rahal Letterman Lanigan's James Jakes, who was similarly penalized as his car was fitted with its sixth new engine of the year. IndyCar rules limit each entry to five engines per season.
Franchitti's problem comes after an engine sensor glitch that compromised Target Chip Ganassi Racing teammate Scott Dixon during the second phase of qualifying on Saturday, although the New Zealander was able to recover and went on to claim pole.
