PRAGUE — Czech Republic captain Tomas Rosicky could miss European Championship qualifiers against Kazakhstan and Latvia in September.
The Arsenal midfielder injured his knee in June in another Euro 2016 qualifying match against Iceland and underwent arthroscopic surgery last week.
Czech football federation head Miroslav Pelta said Wednesday that "we have information from Arsenal that everything is getting better but time is against us."
Arsenal manager Arsene Wenger said last week that Rosicky was "on a progressive recovery."
Rosicky's agent, Pavel Paska, told Czech newspaper Mlada Fronta Dnes on Wednesday that the player's recovery should take 4 to 8 weeks.
The Czechs are second in Group A, trailing Iceland by two points and three points ahead of the Netherlands in third.
