The inspirational Dutch midfielder may also not have recovered from his calf injury in time for the huge upcoming game with Manchester United
Talksport have reported that the Dutchman has responded slowly to treatment on the injury, picked up during Spurs' 3-1 win over Wigan last month.
Van der Vaart, who has scored nine goals this season, is definitely out of this weekend's FA Cup fifth-round tie with Stevenage and faces a race against time to prove his fitness to manager Harry Redknapp ahead of next week's North London showdown with Arsenal.
Spurs host the Red Devils a week later at White Hart Lane, and if the 29-year-old fails to make the team for the trip to the Emirates, it is widely believed that the best he could hope for against United would be a spot on the bench.
