This was after their arbitration case, where they wanted the two opening league games which they did not honour replayed, was dismissed on Sunday.
Prior to the arbitration case starting, the KwaZulu-Natal side withdrew and said they were going to interdict the play-offs from taking place. In terms of the laws of the game, arbitration is final and binding. This could create problems for Thanda, including a possible expulsion from the league as Fifa is clear that football matters cannot be resolved in the courts of law.
Fifa has created arbitration as a platform where disputes are resolved.
The promotional play-offs start tomorrow with a Cape Town derby featuring Chippa United and Santos at Philippi Stadium. The other team participating in the three-team play-offs is Mpumalanga Black Aces, who were relegated to the NFD from the Premiership in 2011.
Thanda Royal Zulu chairman Pierre Delvaux was yesterday attending a series of meetings with his legal team, but insisted the club will push for the play-offs to be temporarily suspended until the issue was resolved.
The PSL refused to comment yesterday, saying they were monitoring the situation.
