The Turkish Grand Prix is expected to be dropped from next year's Formula 1 calendar after teams were told it was no longer on the itinerary.
A schedule handed out by F1 boss Bernie Ecclestone includes 20 races, rather than the 21 on the original list.
McLaren managing director Jonathan Neale said: "It is always sad when you lose a grand prix from the calendar. We are sorry to see Turkey go."
Turkey has hosted a race since 2005 but attendances have been poor.
It had been on a 21-race schedule released by governing body the FIA in June, which includes the inaugural United States Grand Prix in Austin, Texas.
But the teams' contracts with F1 dictate there can be no more than 20 grands prix in a season.

Virgin Racing chairman Graeme Lowdon said: "The calendar already has 20 races, as a smaller team 21 is too many."
The Bahrain Grand Prix, which was scheduled to be the opening race of the 2011 season before being cancelled because of the civil unrest in the country, has been pencilled in for late in the 2012 campaign.
Autosport has reported that it has now been moved to a new date as the third last race on 4 November.
The magazine added that the US race, originally scheduled for June, would now be the penultimate race on 18 November, a week before the season climax in Brazil.
That was in response to concern about the high temperatures in Texas in June.
