RUSSIA are waiting on the fitness of goalkeeper Igor Akinfeev ahead of their opener against the Czech Republic.
The CSKA Moscow man has a knee injury so Zenit Saint Petersburg's Vyacheslav Malafeev is on standby.
The Czechs will wait to assess former Liverpool forward Milan Baros who limped out of training with a thigh problem.
Captain Tomas Rosicky had been a doubt but is now fit after a calf problem.
Russia recorded an impressive 3-0 friendly win over Italy last week but coach Dick Advocaat was in cautious mood.
"One friendly victory, even if it was a thrashing of Italy, doesn't make us the Euro favourites," said Advocaat.
"We should remain realists, it was just a warm-up game.
"It's good that we scored three goals against Italy to boost our team's self-confidence but we still need to improve our defence to avoid serious problems in the group matches with the Czechs, Poland and Greece."
Arsenal's Rosicky believes fellow Gunner Andrey Arshavin remains the key threat to the Czechs.
He said: "When you watch matches of the Russian team, Andrey is still the key player in the national team; there's no doubt about it."
