Tottenham boss Andre Villas-Boas is waiting on the results of a scan carried out on Mousa Dembele's troublesome hip.
The niggling complaint, which has carried over from the Belgium international's time at Fulham, kept him out of Saturday's derby date with Chelsea.
Dembele, who linked up with Spurs in a £15million deal on deadline day, aggravated the knock during a World Cup qualifying clash with Scotland.
It is unclear how long the versatile forward will be sidelined for, but Villas-Boas is hoping his medical staff will be reporting back with positive news.
"Top players are missed," said the Portuguese tactician.
"He had a scan, but we haven't see the results yet. He suffers discomfort and pain on his hip, which is not something that shows on the scan so it's difficult to assess.
"Fulham took him off for a period of two weeks (in January). He had a chance to play (against Chelsea) and had a late fitness test, but the pain didn't go away.
"It's something that comes back to him. He fell awkwardly in the Scotland game against Belgium and felt the pain."
