Spartak Moscow third-choice keeper Artem Rebrov will face Benfica in tonight's Champions League Group G match after Sergei Pesyakov was ruled out with a foot injury.

"Unfortunately, Pesyakov's original diagnosis of a suspected foot fracture was confirmed," Spartak spokesman Alexei Matveyev said.

Pesyakov, who was in goal for Spartak's 3-2 home defeat by Celtic, suffered the injury in a 2-1 loss to Russian league leaders Anzhi Makhachkala on Saturday.

Spartak's first-choice keeper Andriy Dykan is sidelined with a shoulder injury.

Spartak's Spanish coach Unai Emery, however, expressed faith in 28-year-old Rebrov, who has seen little action for the Moscow club since joining last year and has never played in European competition.

"It's not like Rebrov has been without any match practice this season as he has played for our reserve team," Emery said.
