[PORTUGAL] Portugal's Nani is the latest star to withdraw from the World Cup when he was ruled out of the tournament with a collarbone injury suffered in training last week.

The 23-year-old Manchester United winger was expected to play a key role for Portugal in support of his former United teammate, Cristiano Ronaldo.

"He is in pain," Coach Carlos Queiroz told Portugal's TVI network. "We carried out tests and the upshot is that he is not fit to compete."

Ruben Amorim of Benfica has replaced Nani on the Portugal roster.

In the last week ...

-- Nani's United teammate, England captain Rio Ferdinand, was forced to withdraw with a knee injury suffered in practice.

-- Arjen Robben suffered a hamstring injury and looks more and more doubtful. He's remained in the Netherlands for treatment.

-- Ivory Coast star Didier Drogba suffered a broken forearm but hopes to play in the World Cup. He was not seen on the sidelines Tuesday during the Elephants' 1-1 tie with Swiss second division club Lausanne.

Teams have until 24 hours before their first game to replace an injured player.

The Netherlands begins its World Cup campaign Monday against Denmark, while Ivory Coast opens against Portugal the next day.
