The tests Dybala underwent today revealed and confirmed an injury to the left rectus femoris.
The player has already started the recovery process and in one or two weeks he will be evaluated again to understand how the rehabilitation is proceeding.
The stop is currently around 4 weeks, but should conditions improve in the next checks it is not excluded that he may try to snatch a call-up for the last matches of Roma before the break.
The World Cup remains at risk, but it is not precluded.
