Caterham Team AirAsia's Davide Valsecchi and Super Nova Racing's Adam Carroll have both been handed three-place grid penalties for blocking during the Friday afternoon qualifying session.
Valsecchi had qualified in 14th place but already had to serve a ten-place grid penalty at the feature race at the Hungaroring in Budapest, Hungary on Saturday afternoon after been found to have caused an avoidable collision with Jolyon Palmer at last week's German print race.
That dropped the Italian driver down to 24th place, and the additional three-place penalty for impeding Romain Grosjean during the final seconds of the Friday qualifying session completes his demotion to the back of the grid where he will start dead last.
Meanwhile, Adam Carroll was also penalised on his second weekend back in GP2 after a three-year hiatus. He was judged to have blocked Stefano Coletti in the same session, and as a result is demoted to 18th position on the feature race starting grid.
Surprisingly, neither Fabio Leimer nor Jules Bianchi were handed penalties for their incident that had been pronounced under stewards' investigation during the session.
Bianchi has become angered when he felt that Leimer was blocking him while the Lotus ART driver was on a fast lap; when he pulled up alongside, he appeared to make a swerve in the Rapax's direction to make the point that he was not pleased, which opened him up to a penalty of dangerous driving - while Leimer could have been deemed to have been blocking.
After review, however, the stewards decided to take no action over this matter.
