Carlos Sanchez is facing a spell on the sidelines after suffering a knee injury in West Ham's 8-0 Carabao Cup victory over Macclesfield on Wednesday, Sky Sports News understands.
The Colombia midfielder sustained the injury during the early stages of the cup tie against the Sky Bet League Two side and was replaced by Declan Rice.
Sky Sports News understands Sanchez is still undergoing tests to discover the full extent of the injury.
Sanchez joined West Ham from Fiorentina in the summer and has featured six times for the club - the majority of which have come from the substitutes' bench.
The 32-year-old joins fellow midfielder Jack Wilshere in the treatment room while Andy Carroll, Winston Reid and Manuel Lanzini remain out.
It leaves manager Manuel Pellegrini with only two recognised central midfielders - Mark Noble and Pedro Obiang - ahead of the home match against Manchester United on Saturday.
Central defender Rice has been deployed as a defensive midfielder this season and is likely to continue in that role against United.
