It was Folarin Balogun , the U.S. striker whose red-card ban was suspended after Trump asked FIFA to review the case. FIFA kept the red card on record but allowed him to play, so he was effectively reinstated for the next match.

What happened

Balogun was sent off after a VAR review in the U.S. win over Bosnia and Herzegovina, which triggered an automatic one-match ban.

After Trump personally urged FIFA president Gianni Infantino to take another look, FIFA suspended the ban for a one-year probationary period instead of rescinding the card outright.

That made Balogun available again for the Belgium match.

Why it got attention

The decision was unusual and drew criticism from UEFA, which said FIFA had “crossed a red line”.

Reuters also reported Trump called the reversal “brilliant” after the ruling.

TL;DR

The player was Folarin Balogun ; his red card stayed on the books, but FIFA lifted the suspension so he could play again.
