The Senegal international suffered the injury last weekend having only just returned from a month out of Premier League action with a similar problem.
“We are still waiting for the results of his scan, but it will definitely not be a couple of weeks,” West Ham manager Slaven Bilic told a press conference on Thursday. “Four to eight, maybe longer.
“We are waiting for the opinion of a couple of specialists. He has a bit of history with that thigh. It’s not a light one unfortunately.”
“Of course it’s a big blow. We are not bad in terms of quantity of injuries, but unfortunately they have happened to key players.”
