Manchester United striker Robin van Persie was substituted during Netherlands' World Cup qualifier against Hungary with a suspected thigh injury, but coach Louis van Gaal insists it was for "precautionary measures".
Van Persie was clattered in a challenge with Hungary defender Roland Juhasz and was replaced by Klaas-Jan Huntelaar at half-time.
The extent of the Dutchman's injury is yet to be confirmed.
Van Gaal told SBS6: "We took off Robin for precautionary measures. It doesn't seem to be too serious, but you never know. We didn't want to take any risks."
Van Persie has scored four goals in three games for United following his £24million move from Arsenal last month.
United are also waiting to find out how serious Shinji Kagawa's back injury is.
Kagawa was forced to pull out of Japan's World Cup qualifier against Iraq on Tuesday, just an hour before kick-off.
A Japan Football Association official had told Japan's Daily Sports: "He felt uncomfortable in his lower back in practice yesterday, and we decided to wait a night and see how it looked, but he's not at 100% so we're leaving him off.
"He didn't go to the hospital."
Kagawa later played down fears that he could be sidelined for some time.
"It [the injury] happened in yesterday's practice," he told Nikkan Sports.
"I was holding the ball and went to make a move and in that instant it started to hurt.
"I won't take long [to recover]."
Man Utd take on Wigan this weekend in the Premier League and are also in action next Wednesday in their opening Champions League match, at home to Galatasaray.
