Fans went on the rampage after Kaizer Chiefs lost 2-0 to Free State Stars in the Nedbank Cup semi-finals, as security guards were assaulted, parts of the venue were torched, cameras were smashed, and players and officials were pelted with missiles in Durban.
Van Der Berg says SuperSport TV are currently assessing the costs they incurred over the weekend.
"We are still try to assess the damage. It might take a while," Van Der Berg tells KickOff.com.
"I can only confirm that it was significant damage."
Meanwhile, SAPS spokesperson Nqobile Gwala has confirmed that one of two suspects arrested in connection with the violence has been released from custody.
"There was nothing linking him to the incident."
