Hammers manager Sam Allardyce confirms that his skipper is set to miss six weeks with a fractured shoulder but is optimistic that his side can cope with his absence
Nolan sustained the injury in training on Thursday and played no part in the club's 3-1 win at Crystal Palace two days later and his manager now says that the midfielder is not likely to return until October, in a "massive blow" for the club.
But Allardyce hopes that the Hammers' excellent win at Selhurst Park shows that they can find a way without their skipper, who has scored 17 goals in 69 top-flight appearances for the club.
"Kevin fractured his shoulder and that's a massive blow to us, along with all the other players we've got injured," he told the press.
"He will be out for probably six weeks, I would think.
"It isn't a dislocated shoulder, it's a fractured shoulder but I don't know just how long that will keep Kevin out.
"We dealt with it brilliantly at Palace and let's hope we can continue to do that. It didn't affect us at Palace and maybe that's a sign there's more to come."
Mark Noble will deputise as West Ham skipper in Nolan's absence.
