West Ham defender James Collins is set to out for a month with a hamstring injury picked up during the 1-1 draw with Tottenham Hotspur on Wednesday evening, according to Gary Jacob of The Times.

Collins, who was deployed as one of three centre-backs thanks to a Slaven Bilic tactical re-shuffle, hobbled off after 65 minutes and was replaced by youngster Reece Oxford.

Losing the Welshman will be a blow to the Hammers as he’s arguably been the club’s best defender this season.

Winston Reid and James Tomkins are both out injured too, so Oxford may be needed to partner Angelo Ogbonna at the heart of the Hammers defence for the upcoming trip to Goodison Park to face Everton.

Joey O’Brien, Carl Jenkinson and Sam Byram are also unavailable for the trip to Merseyside, so Bilic will have to put together a make-shift defence as he tries to get his side into the Champions League next season.
