Paraguay’s Miguel Almiron became the first player to be shown a red card for covering his mouth while speaking to an opponent during his side’s World Cup group match against Turkey in San Francisco.
Almiron, 32, obscured his mouth with his hand while speaking to Turkey’s Mert Muldur, who immediately informed an official standing next to him.
Following a check by the video assistant referee (VAR), referee Ivan Barton from El Salvador announced to the crowd that he was sending off the former Newcastle United winger.
The incident occurred just before half-time with Paraguay leading 1-0.
Commentating for BBC Radio 5 Live, former Republic of Ireland striker Clinton Morrison said: “If you know the rules, you shouldn’t do it. You’ve got to credit the referee and the VAR for making that decision.
“Not everyone would agree with it, but if those are the rules, you’ve got to stick by the rules.”
