Germany midfielder Torsten Frings failed a fitness test before the Euro 2008 quarter-final against Portugal but forward Lukas Podolski was cleared to play after recovering from a calf muscle injury.
Frings, who fractured a rib in the 1-0 win over Austria, was replaced by Simon Rolfes in the centre in one of three midfield changes for Germany.
Coach Joachim Loew, banned from the touchline, moved Podolski up front to replace Mario Gomez, with his spot at left midfield going to Thomas Hitzlsperger. Bastian Schweinsteiger has come in on the right for Clemens Fritz.
Portugal coach Luiz Felipe Scolari, as expected, named an unchanged team from that which started in the victories over Turkey and Czech Republic, most of whom were rested for the final group match against Switzerland, a 2-0 defeat on Sunday.
