Tottenham Hotspur's official Twitter account has said that Heung-Min Son is currently undergoing a spell of rehabilitation treatment, after picking up a foot injury against Manchester City.
Son was substituted in the second-half of the Lilywhites' match against City, but there were few signs that he was carrying a serious injury.
However, it appears that the South Korean could be set for a spell on the sidelines, as the Tottenham medical team continue to assess the severity of his current problem.

If Son is ruled out for a considerable period of time it would be a huge set-back for Spurs, as he has made such a good start to life at White Hart Lane.
The 23-year-old has added a new dimension to the Lilywhites' attack, and has already scored three times in his first five games.
It is not just Son's goalscoring which has impressed, though, as the attacking midfielder has also shown a tireless attitude when on the pitch.
It appears that he is almost certain to miss Tottenham's Europa League match against Monaco on Thursday, while his involvement in a Premier League clash with Swansea City on Sunday could also be in doubt.
