Angel Di Maria could defy the odds to be fit to play in the World Cup final, according to Argentina's team doctor, while Sergio Aguero has been passed fit to face Netherlands in the semi-final on Wednesday.
The Real Madrid winger, 26, only made it through 33 minutes of the Albiceleste's quarter-final with Belgium, which they ultimately won 1-0.
After the match, his agent Eugenio Lopez suggested the Real Madrid man had torn his thigh muscle and would not recover in time to feature in the final if they are able to beat Netherlands in the last four.
Di Maria underwent medical tests on Sunday and is reported to be desperate to be fit should Alejandro Sabella's men get past the Dutch to play against Brazil or Germany at the Maracana on June 13.
Daniel Martinez, Argentina's team doctor, gave a much more optimistic outlook towards Di Maria's injury than the player's agent had originally given, however, insisting that there remains a possibility he could be back in action in a week.
"Di Maria, like Sergio Aguero, has a light injury," he told reporters. "It is one of the mildest muscular injuries.
"He won't play in the next match. After that we'll look at him on a day-by-day basis."
Di Maria has been an ever-present in Sabella's starting line-up in Brazil and scored the winning goal in extra-time against Switzerland in the last-16.
Martinez also gave good news regarding Aguero, who has struggled with injury throughout the World Cup, by revealing he should be fit to feature against Louis van Gaal's men on Wednesday.
"He's done three team training sessions now and we hope that continues with his recovery," he added. "He's ready to play."
