CAMPINAS, Brazil -- Cristiano Ronaldo cut short a training session with Portugal on Thursday, to add weight to the suggestion that he will not be fully fit ahead of their first game against Germany on Monday.
Ronaldo trained with the rest of the team for about 15-20 minutes doing physical exercises but then did not take part in the rest of the session with full ball drills.
Instead, he stretched on his own and signed a few shirts for fans before going to sit on the bench. When he left, he had an ice pack over his left knee -- indicating that his tendinosis is still bothering him.
However, Portugual midfielder Joao Moutinho said there was nothing to worry about concerning Ronaldo's health.
"Ever since he started to train with us he has been 100 percent like the rest of us," Moutinho said. "Everything is fine with him but there is some caution, not only with him. Today many other players were using ice as well. There is nothing to worry about. The ice is normal after training."
Defender Fabio Coentrao missed training with a suspected hip injury.
The full-back scored in his country's final FIFA World Cup warm-up fixture -- a 5-1 triumph over the Republic of Ireland on Tuesday -- but there will now be fears over his fitness ahead of Portugal's tournament opener against Germany on Monday.
However, Portuguese federation vice president Humberto Coelho was quick to allay those concerns, a day after the national team arrived in Brazil.
"It's nothing to worry about," he insisted. "It's just a one-off situation. Quickly he will be fine and back to training."
