West Ham have been dealt a massive injury blow with the news Dimitri Payet could be ruled out for three months.
The French midfielder has been a major factor in West Ham's fine start to the season following his ?10.7million summer move from Marseille.
But Payet, who has hit five goals in 14 appearances, suffered an ankle injury after a challenge from James McCarthy in the 1-1 draw against Everton on Saturday.
And Jack Sullivan, the son of Hammers co-owner David Sullivan, revealed the extent of the 28-year-old's injury on Twitter.
He wrote: "Sadly Payet will be out for about 3 months! Huge miss for the team. How the Everton player didn't get sent off amazes me!!"
Ecuador forward Enner Valencia was also injured against the Toffees with the club awaiting the results of a scan on his ankle problem.
