Portuguese striker ruled out with 'muscle injury'

Portugal striker Helder Postiga has been ruled out of next week's Euro 2012 semi-final through injury, the Portuguese football federation have confirmed.

Postiga was replaced just before half-time during last night's 1-0 quarter-final victory over the Czech Republic after suffering what the FPF have announced is a "a muscle injury to the back of the right thigh."

The Real Zaragoza striker will now sit out the semi-final against either Spain or France next Wednesday.

Postiga has started all four of Portugal's matches in Poland and Ukraine, scoring once in the 3-2 Group B victory over Denmark.
