Diafra Sakho: West Ham man expected to miss 'four to eight weeks'

West Ham striker Diafra Sakho could be out for more than two months after injuring a thigh during Sunday's match against West Brom.

The 25-year-old pulled up after taking a shot and was substituted in the 17th minute of the 1-1 draw at Upton Park.

"It will definitely not be a couple of weeks - four to eight, maybe longer," said manager Slaven Bilic.

"We are waiting for the specialists. He has a bit of history with that thigh. It's not a light one unfortunately."

The Senegal striker has scored five goals in 14 appearances for the Hammers this season.

West Ham are already without midfielder Dimitri Payet, who has been ruled out until February with an ankle injury.

Ecuadorian striker Enner Valencia is also sidelined by an ankle problem.

"Of course it's a big blow," Bilic added. "We are not bad in terms of quantity of injuries, but unfortunately they have happened to key players."
