West Ham are hopeful that Kurt Zouma will be back for the game against Wolves on January 14 at Molineux.
But the hospital visit took place later in the week and there is usually a six week recovery period for such issues.
The player is still not training and there seems little chance of him being ready for Christmas and early new year games.
However, there are hopes that Nayef Aguerd will have recovered from his thigh injury in time for the game against Arsenal.
However it seems more probable that he will be available for the game against Brentford at the London Stadium or the away game at Leeds on January 4.
With both central defenders unavailable it would mean that either Thilo Kherer or Ben Johnson would partner Craig Dawson in the festive games.
