The Chelsea midfielder have spent two months on the sidelines with a hernia surgery but he suffered another setback on his comeback when he suffered an adductor muscle injury during training on Thursday. The latest injury is set to keep Lampard out for about two to three weeks.
“Frank is not fit,” Ancelotti said. “He had a problem during the session. He had done a fantastic session yesterday but then had an abductor problem. We have to wait for him.
“I think he will be out for three weeks, until December. It is not what we wanted because we hoped to use him with Michael Essien suspended, but now we cannot.”
He added: “Frank had a problem with his adductor. He does not need surgery.”
More bad news for Chelsea as Alex will also not feature in the match against Sunderland but Nicolas Anelka will be able to come back after he recovered from a back problem.
