CSKA Moscow midfielder Alan Dzagoev will be sidelined for at least six weeks with a toe fracture, a little more than two months before the start of Euro-2012, the club reported on Friday.
On Thursday the 21-year-old playmaker was at a German hospital to undergo surgery on his toe, which he broke during a Russian league match against Lokomotiv Moscow last weekend.
CSKA medical staff said Dzagoev, a Russian international, will need no less than four weeks for recovery.
Dzagoev's injury is a serious blow for the Red Army side's manager, Leonid Slutsky, who has already lost Japanese playmaker Keisuke Honda to a hip injury.
The injury also added to the woes of Russia coach Dick Advocaat as two Spartak Moscow midfielders, Diniyar Bilyaletdinov and Sergei Parshivlyuk, who are candidates for a place in the Russian squad were also sidelined with injury last week.
