West Ham striker Andy Carroll faces three months on the sidelines due to required ankle surgery.

The Hammers forward played and scored as Manuel Pellegrini's side were beaten 3-2 by Swiss side FC Winterthur in their first match of pre-season on Sunday.

But he reported further discomfort in his ankle and scans have revealed he requires surgery.

Head of medical Richard Collinge said: "Andy played and scored in Sunday's match but is still reporting some discomfort in his ankle and further scans have revealed that he requires some minor surgery to provide more strength and stability to the area."

Defender Winston Reid will also sit out for a minimum of three months as he undergoes surgery on his knee from a problem he picked up last term.

Collinge added: "Winston has been suffering some swelling around the knee injury that he sustained at Swansea last season and he too is in need of explorative surgery to clean up the area.

"We have decided that this is the best course of action to ensure that both players have a chance of returning to full fitness as soon as possible."
