Toby Alderweireld has revealed that he does not know when he will be able to return to action for Tottenham Hotspur.
The Belgium defender has been out of action since sustaining a hamstring injury in the 3-1 win over Real Madrid on November 1.
Spurs have struggled in the Premier League since Alderweireld was ruled out, with their only win coming against struggling Crystal Palace at Wembley Stadium.
The 28-year-old will have another scan on his injury later this month and is hoping to get a clearer picture of the length of his absence.
"I have a serious muscle tear. There's a big chance of recurrence," Alderweireld is quoted by Sky Sports News as saying.
"If the muscle tears off completely, for instance, I would need surgery and it'll take 14 weeks to recover. That's why we try to see how we can treat the muscle.
"I don't have a deadline, because it's dangerous to make it worse. So we have to work hard, but in a controlled way. In two weeks there's a scan to see how it goes. I only try to be on the pitch as fast as possible."
Spurs have limited options at centre-half, with only Jan Vertonghen, Eric Dier and summer signing Juan Foyth fit, while Davinson Sanchez could be banned after receiving a straight red card in the 1-1 draw at Watford on Saturday.
