This follows a report in The Star earlier this month that Ncobo had instructed referees to garner damaging evidence against Orlando Pirates which could get the club in trouble.
A statement read: “The League has appointed a task team comprising Zola Majavu and Michael Murphy (both lawyers) to establish the facts pertaining to this matter.
“Ncobo has also been informed of this and he has indicated his preparedness to assist as required and also stated that he has no objection to the members of the task team.
“The League has been informed that a public polygraph test is to be conducted at the Johannesburg offices of Independent Newspapers at 13h00 on Thursday. It is important for the League to record that such a test is not a part of the investigation which the League has initiated.”
