Kings hooker Michael van Vuuren is set to take legal action against the struggling franchise over the non-payment of his salary.
Van Vuuren, 24, stated that he had been left "financially embarrassed" after failing to receive his salary for October and November from the Kings.
The former South Africa U20 star spent two years in the Top 14 with Stade Français before returning home, but Van Vuuren has now exercised an option in his contract to leave the side.
"Approximately 19 months ago I relocated from France to return to my country and the province and city i grew up in," Van Vuuren said in a statement.
"I did so with my fiancée in tow and with the intention of representing my province at Super Rugby and Currie Cup level. I was proud and excited by my return to Nelson Mandela Bay and looked forward to committing to Eastern Province rugby.
"However the events of this year have left me disillusioned.
"Unfortunately I am no longer in a position to accept non-payment of monies due to me and the present climate of uncertainty. These monies are the life blood of my existence.
"The non-payment of monies due to me for October and November have left me financially embarrassed. I am no longer in a position to rely upon my friends and my family.
"The shroud of mystery that surrounds the sponsorship issue, the broken promises and continued financial issues as well as the constant reference to liquidation has rendered my position untenable.
"Unfortunately the executive is in material breach of my contract and in the circumstances I have no choice but to cancel my contract and exercise my legal remedies."
