Ferrari will not appeal Sebastian Vettel's five-second penalty which cost him victory in the Canadian Grand Prix.
Vettel was demoted to second behind Lewis Hamilton after he was punished for rejoining the track in an unsafe fashion.
Ferrari lodged their intention to challenge the stewards' controversial verdict following the race at Montreal's Circuit Gilles Villeneuve.
But it is understood that, ahead of Thursday's deadline, Ferrari have informed the FIA, Formula One's governing body, that they will not press ahead with their action.
Vettel fell off the track at the first chicane while defending his lead from Hamilton on lap 48 of Sunday's race.
The Mercedes star called his Ferrari counterpart's driving dangerous, saying he had to slow down to avoid a collision.
Vettel protested his innocence, describing the stewards as "blind", before swapping the first and second-place markers around after the race, and initially swerving the podium celebrations.
