Rosicky did not feature in Czech Republic’s 4-2 Euro 2016 qualifying win over Kazakhstan on Monday after revealing he suffered a calf problem in the build-up to the game.
Rosicky said: “I couldn’t do any sharp movement, couldn’t sprint. If I tried to play in one tempo, I wouldn’t make any difference for the team.
“I’ll come back to London and we’ll see. The doctor said I have something swollen between the muscles.”
The midfielder joins Mesut Ozil, Laurent Koscielny and Danny Welbeck in picking up injuries during the international break.
The 34-year-old has only made one start for Arsenal this season, in the League Cup defeat by Southampton.
