The England international’s season was derailed early on after missing the first two months with knee ligament damage and has not featured for Spurs since the Boxing Day win over Southampton.
The 27-year-old is set to again miss out against London rivals West Ham in the Premier League on Thursday, as well as Sunday’s FA Cup third-round tie against AFC Wimbledon at Wembley.
Speaking after Tuesday’s 2-0 win over Swansea City, Tottenham boss Mauricio Pochettino said: "We need to assess him. After the game against Southampton it was impossible to train and now we are going to assess him. Then the club will give information about what has happened.
"I am concerned about everyone when they cannot be available to play. Sometimes it is small things. You know in this situation we cannot manage because I am not a specialist. I am not a doctor.
"Always you are worried because you want the players available and fit to play, so you can make your decision. But we need to wait and we will assess him in the next few days."
