Tottenham defender Younes Kaboul picked up a knee injury during their Europa League win at Anzhi.
The only negative on the night was a knock sustained by Younes Kaboul, forcing him off 20 minutes from time at the Saturn Stadium.
The Frenchman has been plagued with injuries for the best part of 18 months and suffered another setback in Russia.
"It's a bit of a problem because of his injury in the knee it has taken him time for his body to adapt to new positions on his run," Spurs boss Andre Villas-Boas said.
"Because of that he's putting extra strain on his muscles and keeps getting small contractions that limit him finishing the games.
"At the moment it doesn't look very serious but it will force him to stop for a week or so.
"When we get him back we will give him a one-week or two-week preparation to be physically better."
