Genoa have lost striker Mattia Destro for at least three weeks after he was diagnosed with a thigh strain.
The young hitman limped off during the opening minutes of Sunday's 1-1 draw with Milan.
Tests today confirmed a second degree thigh strain to the right leg and will begin rehabilitation treatment on Monday.
Destro is expected to be out of action for at least three weeks.
There was some good news from the Genoa treatment room, as Luca Antonelli is almost ready for his Serie A debut with the club.
The January signing from Parma took part in a game between ranks today.
