The Arsenal midfielder has had trouble with injury in the past and now seems like he may be in doubt once again.
“The muscle is not torn but it is necessary for me to consult a doctor,” said Rosicky.
“After that all being well I will rejoin the squad.
“For the moment there is no great panic as regards the fitness of Rosicky.
“But if towards the end of the week Tomas is still not 100 per cent ready then Darida will be selected for the Euro, at the expense of an already selected player.”
