Switzerland are without their captain Alex Frei, who has a knee ligament injury and is likely to be replaced by attacking midfielder Hakan Yakin. Frei's regular strike partner Marco Streller has a groin problem but is expected to recover in time to play.
Turkey defender Gokhan Zan will miss out after injuring his knee in his side's opening match against Portugal and Emre Asik is set to deputise. Fellow centre-back Servet Cetin is also doubtful with a knee injury.
