Paul Pogba rejoined Juventus this summer on a free transfer, six years after departing the Old Lady for Manchester United.
But the Frenchman's return to Turin hasn't quite gone to plan, with the 29-year-old suffering a serious injury in training this week.
As a result, Pogba will need to undergo surgery, forcing him to miss out on not only the rest of Juventus' pre-season schedule, but also the start of their Serie A campaign.
The club confirmed Pogba's injury via social media on Sunday, stating that he'd suffered an injury to his meniscus.
"Following complaining of pain in his right knee, Paul Pogba underwent radiological examinations that revealed a lesion of the lateral meniscus," the club confirmed on their official website.
"In the next few hours he will undergo a specialist orthopedic consultation.
"Therefore, in order to continue treatment, he is not taking part in the trip to Dallas."
Juventus face Barcelona, Real Madrid and Atletico Madrid in the coming week, before starting their season on August 15 against Sassuolo.
With the World Cup also starting in November this year, Pogba could face a race for fitness to feature in the France squad in Qatar.
