The probe into the alleged match-fixing of Premier Soccer League games is unlikely to be concluded before the promotion play-offs wrap up on Wednesday.

This is after the PSL chief executive Brand de Villiers confirmed yesterday that investigators were "still busy" looking into a complaint made by Moroka Swallows two weeks ago.

The claims became public earlier this month after it emerged that the Dube Birds accused Free State Stars of influencing the outcome of a match in the final weeks of the season.

Swallows then teamed up with relegated side AmaZulu in a court bid on the eve of the play-offs in an attempt to stop the matches from taking place.

The Johannesburg High Court struck the interdict off the roll and ordered the two clubs to pay the PSL's costs of opposition.

"The investigators are still busy with the interviews," said De Villiers. "These allegations have got nothing to do with the play-offs.

"Our rules are clear that if a team finishes at the bottom of the log, then they will get relegated. And if a team is second from bottom, then they will be involved in the play-offs. That hasn't changed."
