Tottenham face the prospect of being without Son Heung-min for several weeks after the forward fractured his right arm in Sunday's win over Aston Villa, the club have announced.
Son suffered the injury in a first-minute challenge with Villa's Ezri Konsa and though he completed the 90 minutes and scored twice, he now faces surgery on the injury and a potential long-term lay-off.
A statement on the club's website read: "Son Heung-min is to undergo surgery this week after sustaining a fracture to his right arm.
"The South Korea international suffered the injury during our win against Aston Villa on Sunday.
"Following surgery, our medical staff shall be reviewing management options for Son's rehabilitation with the player expected to be sidelined for a number of weeks."
The injury leaves Tottenham desperately short up front, with first-choice striker Harry Kane also a long-term absentee with a hamstring injury.
Son has been deputising as the main frontman since Kane's injury but with both players now missing, Lucas Moura or untested youngster Troy Parrott may be required to step in.
Manager Jose Mourinho said last month that Parrott is "not ready at all" to fill the void as the main striker, though the Republic of Ireland Under-21 international could be considered for some playing time.
