Juventus midfielder Claudio Marchisio is a doubt for the crunch clash against Inter at the weekend, according to calciomercato.it.
The 25-year-old underwent an ultrasound that revealed a muscular injury to his left thigh, which is expected to keep him out of action for three to five days, putting his presence in the Derby d'Italia at risk. He had already been omitted from Italy's squad to face Germany in a friendly as a precaution.
Despite the Bianconeri's inconsistent displays in 2011 thus far, Marchisio has been one of their in form players in recent matches and his energy in midfield will certainly be missed by coach Luigi Del Neri if he is unavailable on Sunday evening.
Marchisio's rising profile has seen him improve in the Castrol Rankings to 178.
