Danny Rose is a major doubt for Tottenham's FA Cup semi-final against Chelsea next month.
The England defender suffered a medial knee ligament injury against Sunderland on January 31 and has still not returned to full training.
Rose is continuing his rehabilitation by training away from the main group and the defender faces an uphill battle to be fit in time for the Wembley clash against Chelsea on April 22.
Rose visited a specialist on Thursday as the club seek to get to the bottom of the issue and resolve the problem.
