Kevin Ceccon has lost his third-place finish in the first Hockenheim GP3 race after being given a retroactive drivethrough penalty.
Last year's Auto GP champion, who looked like he had claimed his second GP3 podium with Ocean Racing Technology in Germany, was ruled to have not had the wheels fitted to his car before the three-minute signal prior to the race.
As the offense was not issued until after the event, Ceccon had 30 seconds added to his race time in lieu of a drive-through, dropping him from third to 17th.
Carlin's Alex Brundle and Jenzer's Robert Visoiu were given drive-throughs during the race for the same offense, but have both now been excluded for not taking the penalties within the mandatory two laps of notification. They had finished 16th and 21st respectively.
The penalties mean that Giovanni Venturini moves up to third and a podium finish in only his second weekend in GP3. His result is also a maiden GP3 podium for the Trident team.
Championship leader Mitch Evans is elevated from ninth to eighth in the race one results, and therefore gains race two pole. His main title rival Aaro Vainio will start fourth on Sunday.
Patric Niederhauser won race one for Jenzer, just ahead of Lotus's Conor Daly.
