Netherlands striker Robin van Persie [ Images ] was taken to hospital on Saturday for a scan on an arm injury three days before their semi-final with Uruguay in Cape Town, coach Bert van Marwijk said.

Van Marwijk said in Johannesburg that defender Joris Mathijsen [ Images ] was also in hospital for a scan on a knee injury.

"Robin van Persie is in hospital at this moment for a scan and Joris Mathijsen is the same. Robin has an arm problem and Joris a knee problem," he said at a press briefing after a training session.

He did not think the Van Persie injury was serious but wanted to see the scan first to be sure.

Netherlands knocked favourites Brazil [ Images ] out of the tournament on Friday with a comeback 2-1 win in Port Elizabeth in which Van Persie played 85 minutes.

Mathijsen had been named in the starting line-up against Brazil but was replaced after being injured in the pre-match warm-up.
