Son Heung-min left the pitch at halftime on 5 June 2026 as South Korea fell behind Mexico, prompting questions about his fitness and the coach’s plan. The captain was replaced after 45 minutes with the score 1‑0 to the visitors, a move that sparked immediate speculation across the football world.

What happened?

South Korea started the friendly at Seoul World Cup Stadium with Son leading the attack. Mexico struck first in the 23rd minute, and by the 44th minute Son appeared to limp after a challenge from midfielder Luis Gómez. Coach Paulo Paquetá signalled a substitution, bringing on Lee Jae‑sung for the Korean star.

Why was Son taken off?

Medical staff ran a quick scan and reported a Grade‑2 hamstring strain. The diagnosis meant any further strain could sideline Son for up to six weeks, a timeline that would jeopardise his participation in the upcoming Asian Cup qualifiers. Paquetá later confirmed the decision was precautionary, emphasizing the need to protect the team’s talisman for the crucial matches ahead.

How does this affect South Korea?

Son’s absence forces the Taegeuk Warriors to reshuffle their front line. Lee Jae‑sung, who scored the equaliser in the 68th minute, will likely retain his place, while veteran forward Hwang In‑gyu may see increased minutes. The tactical shift could alter South Korea’s pressing rhythm, as Son’s pace and work‑rate have been central to their high‑intensity style.

What’s next for Son?

The Korean Football Association announced that Son will undergo a targeted rehabilitation program, with a tentative return date set for the next international window on 20 July 2026. If he recovers on schedule, he could feature in the crucial World Cup qualifying playoff against Japan. Fans will be watching his recovery closely, as his leadership and goal‑scoring record remain vital for South Korea’s ambitions.

How will Mexico respond?

Mexico’s coach, Jaime Luna, praised his side’s disciplined defense that forced the substitution. He hinted that the Mexican squad will use the friendly as a springboard for the upcoming CONCACAF Nations League, where Son’s absence could give them a tactical edge.

The incident underscores the fine line between player welfare and competitive urgency. Son’s early exit may be a setback, but it also offers South Korea a chance to test depth ahead of the decisive fixtures that lie ahead.
