Red Bull's plan of giving its young driver Dan Ticktum a run in an F1 car at the end of the month in Hungary has been opposed by the FIA.
Helmut Marko has been eyeing the 19-year-old, who currently competes in the European F3 Championship, as a potential replacement for Brendon Hartley in 2019.
In order to bring the young charger up to speed, Red Bull planned on running the Brit at F1's in-season test scheduled at the Hungaroring on July 31 and August 1, but the FIA's super-licence rules will preclude Tictum from taking part.
"He drives great races in Formula 3 but has not yet scored the points for the license," Marko told Auto Motor und Sport.
"How are we supposed to bring our young drivers to Formula 1?"
If Tictum is restricted from running in Hungary, Marko will pencil him in for the end-of-season test in Abu Dhabi.
As a teenager, Tictum made headlines back in 2015 when he was hit with a two-year ban, the second of which was suspended, for deliberately crashing into an MSA Formula championship rival.
Since, the young hopeful has put himself back in gear and rebuilt his career, in no small part thanks to Red Bull and Helmut Marko.
"It's no coincidence that his programme has proven so successful," said Ticktum.
"I think it's his philosophy for young drivers -- urging them to get on with things, and the lessons he gets them to learn.
"I know I'm quick enough and good enough to make F1, but I need to focus on some pieces of the puzzle -- but I'm a lot closer to the finished article," he said.
