Inter could be without Diego Forlan for two weeks after he picked up an injury on international duty.
The striker netted his 32nd goal for his country to become Uruguay's record scorer in the 1-1 draw with Paraguay, but he ended the night on the treatment table.
The summer signing from Atletico Madrid picked up a muscle problem in the tie and he'll be sidelined for at least the next 14 days.
Forlan will thus definitely be out of this weekend's trip to Catania and also the home tie versus Chievo.
If all goes well with his recovery then he'll either return at Atalanta or at home to Juventus in Week 10.
His injury will make no difference to his club's Champions League campaign, though, as he's not eligible to play in that competition until after Christmas.
