Spartak's Alex out of Chelsea clash

MOSCOW, Oct 17 (Reuters) - Spartak Moscow playmaker Alex will miss Tuesday's Champions League match against Chelsea with a thigh injury, the Russian Premier League club said on Sunday.

"Medical tests, which were done on Saturday, revealed a minor tear," Spartak coach Valery Karpin told local media.

"He'll need about seven to 10 days to recover."

The Brazil international was substituted at half-time in Friday's 3-0 league win over Alania Vladikavkaz shortly after scoring Spartak's second goal.

Alex's withdrawal has added to Spartak's mounting injury worries ahead of the top-of-the-table Group F clash against the English champions in Moscow.

The Muscovites could also miss leading striker, Alex's compatriot Welliton, who is yet to recover from a pulled thigh muscle, and Ireland winger Aiden McGeady, who did not play against Alania because of a leg injury.
