West Ham forward Enner Valencia is expected to return from a knee injury early in the new year.
Valencia was taken from the field on a stretcher during West Ham's 1-1 draw against Everton before the international break, less than 20 minutes after replacing Dimitri Payet who suffered an ankle injury.
It was only Valencia's second game back after sustaining a knee injury in July, which kept him out of action for three months.
The Ecuador international subsequently met with a specialist on Monday and he is now set to begin his rehabilitation.
"Valencia was advised that he needs an extended rehabilitation period, which has now begun," West Ham said in a statement on their official website.
"It is expected that he will be fully recovered by the beginning of the new year."
