West Ham are waiting to hear the extent of the injury suffered by Diafra Sakho against West Brom on Sunday.
Sakho limped off with a thigh problem after stretching to shoot into the side-netting during the second half of the 1-1 draw at Upton Park.
It’s another blow to the Hammers’ attacking options, after playmaker Dimitri Payet and winger Enner Valencia were hurt against Everton earlier this month.
Senegal forward Sakho is now set to see a specialist to determine how long he will be on the sidelines, with manager Slaven Bilic admitting it “doesn’t look good”.
“You can see injuries in every club and to be fair the number who are missing is not a lot, but the ones missing are key players who play in the same position,” added the boss.
“Valencia, Payet, and now Sakho. It is very hard to replace them.”
