Cape Town - Striker Sergio Aguero will take no part in Argentina's last-16 encounter against Switzerland due to a hamstring strain.
Aguero suffered the injury during Wednesday's Group F fixture against Nigeria, with the Manchester City ace forced from the field in the first half of Argentina's 3-2 victory.
There were reports that 26-year-old would be ruled out of the remainder of the tournament, but Argentina's medical staff have moved to quell such fears.
"It's a first-degree muscle strain in his femoral biceps," team doctor Daniel Martinez told reporters.
"It's a degree lower within the muscular injuries.
"He will try to recover as soon as possible."
However, while hopeful that Aguero would be fit to take part in a quarter-final clash should Argentina beat the Swiss, Martinez conceded that it was hard to predict how quickly the forward would recover.
"We have several (treatment) alternatives that we will evaluate regarding how it develops," he explained.
"We have all the available resources in order to get Sergio fit as soon as possible.
"The recovery already started on Wednesday.
"From Switzerland onwards, it will depend on whether Argentina remains in the competition and on his day-to-day recovery in order to see him back on the pitch."
