The World Cup quarterfinals kick off on Friday, but even if some players' teams advance, they individually may not reach the semifinals because of yellow cards.
If players who have received one yellow card thus far in Russia are given their second, they will be banned from their next match. Yellow cards are only wiped after the quarterfinals, which ensures that only players sent off in the semifinal would miss the final.
All eight teams in the quarterfinals have players facing this scenario. Notable players on the list include Brazil's Neymar and Philippe Coutinho, as well as France's Paul Pogba and Olivier Giroud and Belgium's Kevin De Bruyne.
