Real Madrid winger Angel Di Maria has been ruled out of all footballing action for four weeks with a hamstring injury.
The 23-year-old suffered the problem three minutes into the second half of Madrid's Primera Liga game against Osasuna at the Santiago Bernabeu on Sunday and was substituted straightaway.
Tests carried out on the Argentina international have now revealed that he has torn his hamstring and club doctors have stated that he will be sidelined for at least four weeks.
Di Maria, who provided the assists in Madrid's first three goals in their 7-1 victory over the Pamplona outfit during the midday kick-off, will miss Argentina's 2014 World Cup qualifiers against Bolivia and Colombia on November 11 and 15 respectively.
He is now set to face a race against time to recover his full fitness for El Clasico against Barcelona at the Bernabeu in just over a month's time.
Madrid are currently in pole position in the league table with 28 points from 11 matches, three ahead of defending champions Barcelona, who are second.
