Heurelho Gomes is to undergo a scan on a groin injury after he fell awkwardly during his team's 1-0 win over Bolton on Saturday. Spurs play Manchester City on Wednesday as both teams battle to finish fourth and qualify for the Champions League.
"Gomes's groin is sore," said Spurs manager Harry Redknapp. "He'll have a scan and see what the damage is. Hopefully he is OK."
Redknapp will bring in Ben Alnwick for the City game if Gomes is unavailable. As well as the 23-year-old Alnwick, Redknapp also has the 36-year-old Jimmy Walker as a back-up goalkeeper.
Redknapp has ruled out trying to emulate City by signing a keeper on emergency loan after the Manchester club brought in Martin Fulop as cover for the injured Shay Given last week.
"If he isn't fit, Ben would play and Jimmy would be on the bench," added Redknapp.
