Spartak Moscow goalkeeper Andriy Dykan has been ruled out of Tuesday's Champions League match against Celtic with a shoulder problem.
The 35-year-old Ukraine international, who picked up the injury during the 3-1 victory over Amkar Perm yesterday, will also miss his side's Group G clash with Benfica on October 23.
An official club statement read: "Today, Dykan had a medical examination which revealed damage to a shoulder joint. He will be out of action for a month."
Spartak are currently bottom of Group G following their 3-2 defeat to Barcelona earlier this month.
