What happened: Miguel Almirón was shown a straight red card in Paraguay's match against Türkiye for breaking FIFA's newly introduced rule that bars players from covering their mouths while speaking. The dismissal came with Paraguay leading 1-0 after Matías Galarza opened the scoring with what was billed as the quickest goal of the tournament. It stands as one of the first sendings-off issued under the new regulation.

Why it matters: The card is an early, high-profile test of how strictly FIFA's anti-mouth-covering rule will be enforced, and it sets an immediate precedent for officials across the rest of the tournament. Reducing a side to ten men over a communication gesture rather than a foul is the kind of call that tends to spark debate about whether the rule is proportionate, and the reaction online was already sharp.

What to watch: Watch for any FIFA clarification on how the mouth-covering rule should be applied after this dismissal, and for whether Paraguay can protect their lead while down a man.
