West Ham are likely to be without three key players for crucial games over the next month, according to Sky sources.
Midfielder Pedro Obiang will miss the rest of the season with an ankle injury. The 24-year-old Spaniard rolled his ankle during the Hammers' 3-2 defeat to Leicester on Saturday and had to be stretchered off.
Defender Winston Reid will be out for between four and six weeks with a hip injury, which forced him to hobble from the pitch against the Foxes.
Winger Michail Antonio was forced to pull out of the England squad with a hamstring injury which is likely to sideline him for up to a month.
West Ham have dropped to 12th in the Premier League after losing three games in a row - against Chelsea, Bournemouth and Leicester City.
They are nine points clear of the relegation zone and have games coming up against Hull City, Arsenal, Swansea City and Sunderland.
