Robin van Persie may miss the Netherlands' friendly with England on Wednesday with a groin injury.
The Arsenal frontman aggravated the problem in an hour-long open training session at Wembley, which hosts the match tomorrow night.
Dutch coach Bert van Marwijk confessed that the 28-year-old striker is a doubt for the game but is hopeful that he will be passed fit to feature.
"We will have to wait and see but I don't think it's too serious. I am optimistic he will play," Van Marwijk said.
Van Persie has been in prolific form for the Gunners this campaign, scoring 29 goals in 25 appearances.
