West Ham will be without Winston Reid for Saturday's clash at Newcastle, adding to the problems for a side without a win in their first two matches and with seven goals conceded, reports the London Evening Standard.
Reid will also miss New Zealand's two World Cup qualifiers against the Solomon Islands but should be fit to return after the international break.
Boss Slaven Bilic sees no need to strengthen the central defensive positions, despite another poor defensive display on Saturday.
"We have enough centre-backs in our team if they stay fit," he said. "You can't have eight players in one situation. We have one position we want to fill unless someone else goes and we have to fill in."
