The United States’ victory over Paraguay featured one of the more unusual uses of video assistant referee technology: a “mistaken identity” review that flipped a yellow card from defender Tim Ream to attacker Miguel Almirón.

The flashpoint came early in the second half. Paraguay broke forward and Almirón drove at the U.S. back line. As he surged toward the box, he tumbled to the turf under apparent contact from Ream, the USMNT captain. Referee Danny Makkelie immediately blew for a foul and produced a yellow card for Ream, seemingly a routine booking for a clumsy trip that halted a promising attack.

In real time, the decision looked credible. Ream was close, Almirón went down, and the speed of the move made it appear that the defender had clipped the attacker’s leg. But in the background, VAR Carlos Del Cerro Grande began a check that would transform the incident.

Under FIFA’s protocol, VAR can intervene not only for penalties, red cards and offsides, but also for cases of mistaken identity: when the wrong player is cautioned or sent off. As the replays rolled, it became clear that Ream had not made contact. Instead, Almirón initiated the fall, exaggerating minimal or no contact in an attempt to win a free kick in a dangerous area.

Having seen enough to question the on-field decision, the VAR recommended an on-field review. Makkelie went to the pitchside monitor, watched the incident from several angles and quickly reversed his original call. Ream’s yellow card was rescinded, and Almirón was booked for simulation.

This sequence showcased a newer, more targeted use of VAR. Rather than simply correcting a foul or penalty, the system was used to protect an innocent player from an undeserved caution and to punish the attacker who had deceived the referee. Former elite referee analysts have highlighted this as exactly the kind of intervention the technology was designed for: a clear, factual correction that improves fairness without re-refereeing every marginal decision.

The outcome sent a strong message. Players who dive not only risk losing a free kick, they now face the prospect of a delayed yellow card once VAR exposes the deception. For the USMNT, it meant their captain avoided a harsh booking. For the wider game, it was a textbook example of VAR’s “mistaken identity” power working as intended.
