RIO DE JANEIRO, June 7 (Xinhua) -- Robin van Persie reportedly underwent medical exams of his troublesome groin on Saturday, raising fresh doubts about his fitness just five days before the World Cup.
The 30-year-old was withdrawn at halftime during the Netherlands' 2-0 friendly victory over Wales on Wednesday.
Despite the move described as a precautionary measure to reporters, the Manchester United striker underwent tests near the team's base in Rio de Janeiro while the rest of the squad worked out in the gym.
"Van Persie is ok, today was only a light session. We will wait until tomorrow to evaluate him better," Netherlands coach Louis van Gaal was quoted saying by news portal Uol.
The Netherlands will begin their World Cup campaign against defending champions Spain in the northeastern city of Salvador on June 13.
Their other Group B rivals are Australia and Chile.
