This after tickets for the much-awaited game were sold out on Thursday.
Kick off is at 8.15pm.
Ferreira tells KickOff.com that only 5,000 tickets were available to fans, for security reasons.
"I want to warn soccer fans with no tickets not to take any chances but stay at home and watch the game on TV," the Wits CEO says. "We have set tight security, plus the presence of the police at the stadium."
The game will be live on SuperSport.
PSL acting CEO Cambridge Mokanyane says: "I can confirm that the Bidvest Wits vs Kaizer Chiefs game is sold out. We have been overwhelmed with the response so far. If someone has not purchased a ticket for this game, they should rather watch it on television.
Mokanyane confirms that tickets for the other TKO last 16 fixtures are still available.
"We urge the fans to use the next few hours to buy their tickets. We are extremely excited about this weekend's TKO fixtures."
