Barcelona's Andreas Christensen has suffered a partial cruciate ligament tear, the club said on Sunday, as Spanish media reports said the Denmark centre-back could be out for months.

Christensen, who picked up a calf issue in October that kept him out for two weeks, twisted his left knee during Saturday's practice session, LaLiga champions Barca said in a statement.

"After tests carried out on the player, a conservative course of treatment has been chosen. The player’s recovery time will depend on his development," the club added.

The 29-year-old started every game for Denmark in this year's World Cup qualifiers, scoring once and providing two assists as they finished second in their group to reach the continental playoffs.

Denmark will play North Macedonia on March 26 in the playoffs, where a win will take them to a final clash against Czech Republic or Ireland for a place in June's World Cup.

LaLiga leaders Barcelona visit Villarreal later on Sunday.
