The Kings still do not know whether scrumhalf James Hall will be returning to the franchise from French club Oyonnax.
The 21-year-old left the Kings after last year's Super Rugby tournament and was supposed to come back in time for the 2017 edition.
However, Oyonnax, who are in France's second division, are now not keen to release him, according to Netwerk24.
There are currently three scrumhalves in the Kings squad – Ricky Schroeder, Johan Steyn and Poerie van Rooyen.
