The Argentinean broke a bone in his foot with an eighth minute tackle, but was not replaced for a further 15 minutes after another blow to the area.

The news adds to Barcelona's injury woes as they are also without striker Samuel Eto'o who is sidelined with a knee injury, while Brazilian midfielder Edmilson was also injured against Zaragoza and will be out for around 10 days.

Barcelona's 3-1 victory against Zaragoza move the Catalans back to the top of the Primera Liga with a one point gap over second placed Sevilla.
