Manchester United record signing Paul Pogba looks set for an extended spell on the sidelines after suffering a serious hamstring injury during the Champions League win over Basel.
Jose Mourinho told reporters that it is a "long-term" injury but the club are yet to give any indication of when he will be fit again.
The Frenchman has reportedly flown out to the USA for treatment whilst many of his Manchester United team-mates link up with their international sides.
France are yet to wrap up their spot at next summer's World Cup but lead Sweden and Holland in Group A as they enter the final round of fixtures.
The former Juventus star began the new season in superb form after a slightly underwhelming 2016/17 campaign.
Pogba enjoyed a holiday with Romelu Lukaku in America last year, in which the pair were repeatedly photographed playing basketball.
Pogba slapped with ban
According to The Sun, the 24-year-old midfielder is under strict orders from Manchester United's medical staff.
They have banned Pogba from playing basketball during his spell out with injury as they believe it could aggravate him hamstring problem.
Manchester United reportedly fear that basketball would put Pogba at risk of muscle strain and stress impact on his knees and ankles, as per The Sun.
Speaking about Pogba’s absence last week, Mourinho said: "We never miss the players that are injured. That’s our way of seeing it. They are injured, we don’t think about them.
"It’s an opportunity for others, is a moment for others to step up and to get the chance, so I think that’s good.
"When we moan all the time about injuries it looks like we don’t trust the other people and we have to."
Meanwhile, the Reds' received some positive injury news regarding star striker Romelu Lukaku, who underwent an ankle scan after linking up with the Belgian national team.
A statement from the Belgium FA read: "Romelu Lukaku underwent an MRI scan but no fracture or structural damage has been diagnosed.
"The next days he will follow an individual training programme.
"It is however too early to state that he won't be match fit for the Bosnia and/or Cyprus game."
