West Ham United defender Razvan Rat is doubtful for Saturday’s match with Chelsea due to the hamstring injury sustained on international duty with Romania.

But defenders Joey O'Brien and James Collins are expected to be fit despite withdrawing from duty with the Republic of Ireland and Wales due to hamstring injuries.

Winston Reid (ankle) could be fit and George McCartney (knee) is back in training, but Andy Carroll (heel), Mladen Petric (thigh), Matthew Taylor (thigh) and Alou Diarra (knee) are absent.
