Mirko Vucinic missed this morning's Juventus training session with flu like symptoms, the club have confirmed.
The Old Lady were back in training at Vinovo on Tuesday ahead of Sunday's Serie A opener at Udinese.
The summer signing from Roma has impressed in pre-season, but he was omitted from training today as a precautionary measure.
It's unclear at this stage whether there is a serious threat that he will miss the trip to the Stadio Friuli.
There was some good news in Turin though, as Simone Pepe trained with the rest of the squad after his recent fitness issues.
