Real Madrid star Gareth Bale is injured again and has been ruled out of coach Carlo Ancelotti's squad to face FC Copenhagen in the Champions League on Wednesday.

In a statement late Tuesday, Madrid said Bale has not trained with his teammates ''because of a sore left hamstring'' and that he would undergo tests on Wednesday.

Bale, the world's most expensive footballer, cost Madrid 100 million euros ($132 million).

The Welshman previously injured his leg during the warm-up for a Spanish league match against Getafe on Sept. 22 and missed the game.
