Portugal are confident Cristiano Ronaldo has not suffered a
serious injury after the winger was hurt in training.
The Manchester United ace is in Belgrade preparing for his
country's Euro 2008 qualifier with Serbia on Wednesday.
During Tuesday's training session, Ronaldo twisted his foot and
suffered an injury to his left heel.
He is now rated doubtful for the game with Serbia, but Portugal are
optimistic it is not a major problem.
"At this time we don't know if he will play," team doctor Onofre
Costa told reporters. "He sprained his heel.
"It doesn't look very serious, but we are not sure if he will be
fit."
Ronaldo scored twice in Saturday's 4-0 win over Belgium, while his
club will also be hoping there is no lasting damage.
The quick-silver attacker is United's top scorer this season and
will be a key player in the club's bid for the Treble.
