Argentina and Switzerland remained deadlocked at 1-1 after 90 minutes in their FIFA World Cup quarterfinal on Saturday, sending the match into extra time as the Swiss were reduced to 10 men following the late dismissal of Breel Embolo.
Defending champions Argentina took the lead in the 10th minute when Alexis Mac Allister headed home from a Lionel Messi corner.
Switzerland drew level in the second half through Dan Ndoye, keeping alive their hopes of reaching a World Cup semifinal for the first time.
The winners of the match will face England in the semifinals on Wednesday in Atlanta. England secured their place with a 2-1 victory over Norway earlier on Saturday.
Shortly after Switzerland equalised, Argentina midfielder Leandro Paredes was initially shown a yellow card for a challenge on Embolo. However, video replays indicated that Embolo had already been falling before any contact was made.
After a review, officials determined that Embolo, who had already been booked earlier in the match, should instead receive the caution, resulting in his second yellow card and a red card. Switzerland were therefore forced to play the remainder of the match with 10 players.
It marked the second time at this World Cup that a yellow card decision was corrected under the tournament's "mistaken identity" protocol, which allows the video assistant referee (VAR) to intervene when the wrong player is shown a yellow or red card.
