Cape Town - Cardiff City and French club Nantes have agreed to extend the deadline on the first instalment of the transfer fee for Emiliano Sala until February 27.
The Bluebirds had been asked to make the first payment of £5.27 million to Nantes on February 20, but it is understood the clubs have agreed to a delay of one week.
Sala was killed when the private plane bringing him to Cardiff crashed into the English Channel on January 21, just two days after his record move to the Premier League club.
In the weeks since Sala's disappearance, the two clubs have been at odds over what has threatened to escalate into a bitter dispute.
Nantes' lawyers wrote to Cardiff on February 5 asking for the first of three annual payments for the player, as was agreed last month, to be paid within 10 working days.
Cardiff, however, has made it clear they want to wait until the investigation into the crash is complete.
They are also querying 'anomalies' in contract details, but club chairman Mehmet Dalman has said they will be 'honourable' with Nantes over the transfer fee if they are contractually obliged to play.
Cardiff says several questions must be answered about the accident, most notably if the pilot was even qualified to be flying with a paying customer in that particular plane and the role of Monaco-based intermediary Willie McKay in the transfer and the flight.
Any wrongdoing in regard to the flight could annul the Welsh club's reported £16m insurance policy for Sala and, if that wrongdoing was another party's responsibility, they may have to sue for compensation.
