Russia have fitness doubts over key players Sergei Semak and Youri Zhirkov for their Group D showdown with Sweden.
Guus Hiddink's side set up a winners-takes-all meeting with Sweden after defeating Greece 1-0 in Salzburg on Saturday.
However, the victory came at a price as captain Semak and defender Zhirkov both picked up knocks.
"That was a tough match and it did some damage," said Hiddink.
"Zhirkov and Semak are uncertain. We will have to see how serious their injuries are.
"It will be a tough game against Sweden. They are tough and they are experienced. The game will be a different game."
