Here's a look at the list of the players who could miss the last-eight matches of the FIFA World Cup

Luiz Gustavo Brazil MidfielderThe 26-year-old midfielder has been a mainstay in the starting eleven. His ability to win the ball back in the middle in the gap between midfi eld and defence will be sorely missed, especially against a Colombia side that has scored 11 goals in just four matches. They will now have to contend with Colombian pace with young attacker James Rodriguez in the lead. Fernandinho and Paulinho have just not had the same impact.Oscar DuarteCosta RicaDefenderNo team will miss a man more than Costa Rica will miss Oscar Duarte. Though they showed great ability to defend (and stay on their feet) with a man down, Greece are no Netherlands, and they do not have a fi t replacement of quality. Despite an underwhelming performance, the Dutch had enough pace and talent to ensure that they saw off Mexico.Marcos RojoArgentinaDefender Argentina coach Alejandro Sabella is in a bit of a tactical muddle as left-back Marcos Rojo will be unavailable for the quarterfi nal clash against Belgium.The side doesn't have a direct replacement for the position. Hugo Campagnaro, Martin Demichelis and Jose Maria Basanta all play in the middle, which means that somebody will have to play out of position to fi ll the void. Rojo had been a constant along with Ezequiel Garay, Federico Fernandez and Pablo Zabaleta.Bastian Schweinsteiger Germany Midfi elder Though coach Joachim Low has said that he will be fi t to play the quarterfi nal despite coming off against Algeria, it remains to be seen if he has the fi tness to last another gruelling match. He had suffered a knee injury during a World Cup training camp.Nigel De JongNetherlandsDefenderIt has been confirmed that Nigel de Jong will miss the rest of Netherland's World Cup campaign with a groin injury. The defensive midfi elder was forced off after only nine minutes into their round-of-16 win over Mexico. Dutch coach Louis van Gaal had already admitted the AC Milan man was a doubt for quarterfi nal match.Roy MillerCosta RicaDefenderCosta Rica's defensive bench has been hit by an injury as Miller has been ruled out of the rest of the tournament with an injury. The New York Red Bulls defender will not feature again, according to reports. This is especially hard as centre-back Oscar Duarte will also not be available as he’s been suspended after he received two yellow cards in the round of 16 match against Greece.NeymarBrazilForwardThe latest on Brazil 's poster boy is that the decision on playing Neymar against Colombia will be taken only at the last minute. He did attend a training session, but his knee was heavily strapped. Memories of the 1998 fi nal against France come to mind, when an unfi t Ronaldo was forced to take the pitch only for the Brazilians to lose 3-0.
