Turkey face the prospect of having just 13 outfield players available for their Euro 2008 semi-match against Germany.
Coach Fatih Terim is waiting to hear whether keeper Volkan Demirel will have his suspension overturned, while Emre only has a 50-50 chance of returning.
Coach Fatih Terim said he may have to field third-choice keeper Tolgan Zengin as an outfield player during Wednesday’s game.
“He could come on towards the end as a sub as last man in defence or a centre forward,” he said.
The Turks were without six players when they beat Croatia 3-1 in a penalty shoot-out in the quarter-finals Friday, and lost a further three – Tuncay Sanli, Arda Turan and Emre Asik – to suspension after picking up yellow cards during the match at Ernst Happel Stadium in Vienna.
Striker Nihat Kahveci was ruled out of the tournament on Sunday with a thigh injury, but Uefa insists it will not be making a special dispensation for Turkey to bolster their squad.
Uefa spokesman William Gaillard said: “You can’t replace any players after the first game of the tournament has been played.
“We know some teams are facing difficulties, but this is a hard rule of the tournament. We have no intention of changing the tournament rules.
“If a team only had eight players to choose from before a match, then we might call an emergency meeting. But we have had no requests and we would find it a bit difficult changing now.”
