Ramos will miss the rest of the La Liga games due to a knee sprain that occurred during the World Cup qualifying match between Spain and Albania.
Spain captain Ramos, 30, was hurt late in the game after falling awkwardly following an aerial duel before he was eventually replaced by Inigo Martinez.
“He has been diagnosed with a grade two sprain of the medial collateral knee ligament in the left knee. His recovery will continue to be assessed,” Real said in a statement.
In the statement, the recuperation period was put at 6 weeks or more depending on doctors orders.
Ramos should miss upcoming La Liga games against Real Betis, Athletic Bilbao and promoted Alaves and Leganes.
He will also miss a Champions League double-header against Legia Warsaw, and Spain’s home World Cup qualifier against Macedonia, and friendly against England in early November.
