Sweden are tipped to lose to France in the round of 16. But they will at least receive support from parts of the Royal Family during the match.
"Prince Daniel and Prince Oscar will attend the Sweden-France match in New Jersey tomorrow," the Royal Family wrote in an email.
The princes also appeared at one of Sweden's training sessions during the World Cup build-up in Stockholm.
Sweden-France will be played at 11:00 PM on Tuesday, Swedish time.
