Liverpool will be without influential midfielder Mohamed Sissoko for three months as he requires surgery on his dislocated shoulder.

As earlier blogged, Sissoko sustained the injury during the 1-0 Carling Cup win at Birmingham on Wednesday after landing awkwardly following a challenge on Medhi Nafti.

'Unfortunately Momo requires surgery which is scheduled to take place next week,' said a Liverpool spokesman.

'It is anticipated he will be out of action for three months.'

Sissoko was sidelined last season when he suffered a serious eye injury during Liverpool's 1-0 defeat by Benfica in the Champions League."
