Turkey lost a Euro 2008 warm-up friendly 3-2 to Uruguay here on Sunday as Fatih Terim s Turks suffered a setback.
Terim rang the changes, fielding only four of the starters who beat Slovakia 1-0 last Tuesday in another German friendly, to see what his squad have in reserve.
Defender Servet Cetin was out injured, as was midfielder Mehmet Aurelio and their absence was keenly felt. Arda Turan opened the scoring with an early header from a cross by Hamit Altintop.
But Uruguay fought back and levelled from the spot on the half hour through Luis Suarez after he was upended by keeper Volkan Demirel.
A fine freekick from Nihat Kahveci six minutes after the restart put the Turks back in front but goals from Suarez on 78 minutes, profiting from defensive disarray, and then a Cristian Rodriguez spotkick five minutes from the end after Emre Asik fouled him, completed a Uruguayan turnaround.
On Thursday the Turks will take on Finland in the German town of Duisburg.
At the Euro, the Turks compete in Group A along with co-hosts Switzerland, 2004 semi-finalists Czech Republic and 2004 finalists Portugal, who they play in their first match on June 7 in Geneva.
