Sakho scored his side's goal in the 1-1 match against Manchester United. He had yesterday his scan and the club has confirmed today that the 26-year-old will miss until the beginning of next year.
"A scan on Tuesday revealed that the injury will keep him out of contention for up to six weeks. It's a big blow for us - he showed against Spurs and Man United what he brings the team. Unfortunately it's a big blow to lose him. I can only hope it isn’t going to be long," said Bilic to the club's website.
