Spartak Moscow goalkeeper Andriy Dikan will be out of action for at least a month after suffering a shoulder injury, the club said Sunday.

The injury puts the Ukraine international out of Tuesday’s Champions League clash against Celtic and Spartak's home game against Benfica on September 23, and at least three Russian league fixtures.

The 35-year-old suffered the injury in Spartak’s 3-1 win away at Amkar Perm and was replaced at half-time by reserve stopper Sergei Pesyakov.

Spartak said a medical examination Sunday discovered damage to the joint capsule of Dikan's right shoulder.

“Consultations are being held with leading European surgeons specializing in shoulder-joint problems,” Spartak said n its website.

Dikan has eight caps for Ukraine and missed his home tournament of Euro 2012 after sustaining severe facial injuries in a clash with Zenit St. Petersburg Alexander Kerzhakov in March.

Another injury doubt for the Celtic game is defender Evgeny Makeev, who has calf muscle problems and will undergo tests Monday.
