The South Korea international has suffered a leg muscle injury.
Antonio Conte subbed Son Heung-Min off in the 79th minute of Tottenham’s 2-0 defeat against Chelsea. However, the Italian boss says the substitution had nothing to do with his injury.
“It was a strange situation,” Conte said ahead of his side’s upcoming game against League One outfit Morecambe.
“Against Chelsea, I made two substitutions together, with Lucas Moura and then Son. But not for injury, the substitutions, but only to try to give them a bit of rest, 15 minutes of rest.
“Then the day after, he felt a bit of pain in his muscle, in his leg. He had a scan and now we have to make the right evaluation from the doctors. He has an injury.
“I don’t know, but probably he will stay without training sessions until the end of this cycle, before the international break.”
The new update means Son will not return for at least a month, a huge blow for Spurs. Son has retained his fantastic form at Tottenham this season, creating more chances than any other Spurs player.
Asked about his side’s activity in the winter transfer window, Conte responded: “The first person who wants to improve the situation is for sure our owner.
“I will have time to speak, also with the people who work within the club to try to understand well the situation, to understand if there is the opportunity to improve this squad in this transfer market. But I think we will do the same thing that all of the teams are doing in these days.
“We have two ways to improve the situation, one is to improve the level of the players that we have in our squad. Another is to implement new players and improve the quality of the squad. But, as you know very well, January is not easy for anyone. So we’ll see what happens.”
Tottenham will return to FA Cup action against Morecambe on Sunday. Conte’s side will then host Chelsea for the second leg of their Carabao Cup semi-final three days later.
