West Ham goalkeeper Lukasz Fabianski sustained a thigh injury in the warm-up before the win against Everton on Friday.
The Polish international had to be replaced by Darren Randolph in the starting line up for the 1-0 victory and he is not expected to be available for Monday’s FA Cup tie against Stockport County.
However, there is optimism that Fabianski could return to fitness for the Hammers’ next Premier League game; when they face Burnley at the London Stadium a week on Saturday.
Ryan Fredericks has tested positive for the virus and was omitted from the squad that travelled to Goodison Park. The fullback remains in self-isolation but a return against the Clarets is likely, unless he continues to suffer from symptoms.
Arthur Masuaku is still in rehabilitation after undergoing surgery on a long-standing knee problem last month. There is still no timeframe on the Congolese international’s return to full fitness.
