SEATTLE (AP) — The Belgian soccer federation is demanding explanation from FIFA about a decision to let U.S forward Folarin Balogun play at the World Cup despite getting a red card in his previous game.

Belgium takes on the United States later Monday for a spot in the quarterfinals.

The Belgian federation said it has still not received either “FIFA’s decision or any explanation regarding this matter. In these circumstances, it has no choice but to challenge the player’s eligibility for the upcoming match.”
