Brendon Hartley has been stepped down from his role as reserve driver for Red Bull's two F1 teams.
The energy drink-owned teams on Wednesday said the New Zealander will be replaced at the remaining races of this season by another teenager, Spaniard Jaime Alguersuari.
Red Bull said it sees the role as "part of its young driver training programme".
"Having benefited from this experience over the first half of the year, Hartley will now concentrate on his own racing programme in the European F3 series," read a statement.
In fact, Hartley only assumed the reserve role in Spain, round five of the 2009 season, due to a hold-up with his super-license application.
