Dutch winger Arjen Robben is out of the Netherlands' UEFA EURO 2008 opener against Italy on Monday in Geneva after suffering a groin strain in training Saturday, the Dutch Football Federation (KNVB) said.

The statement, carried on the KNVB website, did not comment on how serious the injury to the Real Madrid star was.

The Dutch, champions in 1988, also have to play Romania and France in Group C.
