Tottenham are still waiting to find out the full extent of Harry Kane's ankle injury.
The Spurs and England striker suffered the problem in Sunday's 4-1 win at Bournemouth and could not be scanned on Monday due to swelling in his right joint.
Spurs hoped to get the injury evaluated on Tuesday but were still not in a position to reveal the full results, meaning their anxious wait could go on into Wednesday.
Given the delay for a diagnosis, it looks highly unlikely that the 35-goal striker will be fit for Spurs' FA Cup quarter-final at Swansea on Saturday, while his involvement in next week's international break also looks doubtful with England set to face Holland and Italy in friendlies.
With the World Cup just three months away, Three Lions boss Gareth Southgate will also be eager to find out how long Kane could be sidelined for.
Both Tottenham and England will be wary of Kane's previous history of ankle injuries. He suffered ligament damage to the same joint twice last season.
Those problems were of differing severity, however, with the first one keeping him out of 10 games, though he was able to return within a month of the second incident.
The latest injury occurred after a collision with Bournemouth goalkeeper Asmir Begovic in the first half of Spurs' win at the Vitality Stadium.
The 24-year-old tried to play on, but was forced to come off and left the ground on crutches.
