Sergio Ramos will be out for a month with a knee injury suffered in Spain's 2-0 win over Albania in World Cup qualifying.

Ramos was taken off with a knock in the 80th minute of the match, with tests later showing a tear in his knee ligament, Marca and AS have reported.

Ramos could miss as many as six matches for Real Madrid.

Ramos had come in for criticism from sections of the Spanish media after conceding his fourth penalty of the season in Spain's 1-1 World Cup qualifying draw with Italy but played well against Albania.
