England left-back Danny Rose is eyeing a mid-August return from the knee injury that’s kept him out since January, and Argentina winger Erik Lamela isn’t expected back until October — meaning he’ll have missed a full year — following operations on both hips.
Now, South Korea international forward Son is also a doubt, with medics in his homeland expecting him to be out for up to three months after getting hurt in last week’s World Cup qualifying loss to Qatar last week.
There are also fears the 24-year-old may miss World Cup qualifiers against Iran and Uzbekistan on August 31 and September 5.
Spurs, however, are not putting a time-frame on Son’s injury and are understood to believe those Korean estimates are longer than he is likely to be sidelined for.
The player is set to be wearing a cast for at least the next fortnight after surgery on his right arm to realign it and stabilize the affected area with plates and screws.
He is due to then miss at least four weeks, which will rule him of Tottenham’s pre-season trip to America, where they play friendlies against Paris Saint-Germain, Roma and Manchester City in Orlando, New Jersey and Nashville.
Spurs kick off their Premier League campaign away to promoted Newcastle on August 12.
