President of the Border Rugby Union, Buntu Ondala was attacked by a group of unhappy players at a tournament in Tsholomnqa.
Ondela was punched several times in an attack by disgruntled players at a Heritage Tournament and required hospital treatment.
The assault is alleged to have related to unhappiness surrounding a ruling by the Border Rugby Union against the players' club in respect to player eligibility.
SARU President Oregan Hoskins condemned the actions of the players in an official statement.
"An assault is unacceptable in any circumstances but for players to take out their unhappiness about an off-field administrative decision in this fashion is outrageous," said Hoskins.
"The matter is now in the hands of the police, as it properly should be, and I hope that this matter will be pursued to the full extent of the law. This is a very sad occurrence and has no place in rugby."
Hoskins said that he expected a report from the Border Rugby Union executive on their plans for the disciplinary action to be taken against any club members who were found to have been involved.
