Jose Mourinho has admitted Harry Kane has suffered a "serious" hamstring injury.
A prognosis for the England captain's injury has not been made public, but reports have claimed Kane could miss two months of action.
And speaking after Sunday's FA Cup draw with Middlesbrough, Mourinho let slip that Kane will not be returning anytime soon.
Mourinho said: "I think it is better for the medical department to speak about it or make an official report.
"The only thing that I can add is that the feelings I had that it was not a small injury were correct.
"It is not a small injury, but I cannot speak about (recovery) times."
