West Ham United have revealed that Enner Valencia will be out of action for up to 12 weeks.

Valencia damaged his ankle and knee when he fell awkwardly in the 2-2 draw with Astra Giurgiu, but the Hammers forward used Instagram to confirm that an operation would not be needed as the club confirmed he could face three months on the sidelines.

Thanks God, today I received great news as I won't need surgery, all the best ! #COYI Me gustaría agradecer a todos por el apoyo y el cariño mostrado en esta difícil situación. Gracias a Dios, hoy recibí la buena noticia de que no me tendré que operar. Saludos para todos !
