Arda Turan's missed penalty in injury time shattered Turkey's hopes of taking a big step to the European Championship finals as they were held to a goalless draw in Austria in Group A.
Victory for the Turks would have sent them four points clear of third-placed Belgium with just two games to play. Instead they will take only a two-point advantage into next month's clash with already-qualified Germany.
Turan's powerful spot-kick was tipped round the post by Austrian keeper Pascal Grunwald in a dramatic finish which also saw Martin Harnik's 84th-minute effort for the home side ruled out for offside.
The Austrians started better, with Ekrem Dag and Paul Scharner both firing wide in the early stages then Marko Arnautovic's right-footed effort being blocked in the box by Yekta Kurtulus.
A shot in the box from Dag was saved by Turkish keeper Volkan Demirel before Turkey gained control and came close through Turan, Burak Yilmaz and Sabri Sarioglu before half-time.
Umut Bulut shot over the bar for the visitors early in the second half but the Austrians also had their chances and a right-footed effort from Daniel Royer was well caught by Demirel.
After Arnautovic saw another chance drift wide Turkey came closest to breaking the deadlock when a Burak Yilmaz effort rebounded off the bar.
Demirel saved well from Arnautovic and Selcuk Sahin just missed the target for the visitors before the game's dramatic conclusion, in which both sides briefly thought they had done enough.
Harnik was denied by the flag before Turan, who had scored the winner deep into injury time against Kazakhstan on Friday with a superb free-kick, was this time the villain from 12 yards.
