Tottenham are still waiting to discover how long Benoit Assou-Ekotto would face on the sidelines amid fears he could be ruled out for up to a month.
Left-back Assou-Ekotto missed Andre Villas-Boas' first win in charge at Reading on Sunday with a knee problem that may require a 'washout' procedure, ruling him out for around four weeks.
Losing Assou-Ekotto, who has barely missed a match in the last four seasons, would be seen as a blow to Spurs' hopes of building on their opening Barclays Premier League victory this term and of progressing in both the Carling Cup and Europa League.
But Kyle Naughton proved an able deputy at the Madejski Stadium, while Jan Vertonghen has played numerous times at left-back for Belgium.
Either could be asked to fill in there for Tottenham's Europa League opener against Lazio on Thursday.
