Cape Town - Proteas batsman Quinton de Kock has withdrawn from his proposed stint with Nottinghamshire at the request of Cricket South Africa.

De Kock had been scheduled to appear in four County Championship matches, including home fixtures against Yorkshire and Essex at Trent Bridge in September.

His withdrawal leaves Nottinghamshire Director of Cricket, Mick Newell, on the hunt for batting power for the final weeks of the season.

"We're disappointed because Quinton is a high-quality player and we would have been stronger with him in the side, but he has a central contract with Cricket South Africa and there is always some risk when you sign a player of his profile," Newell told the county's website.

"We would like to strengthen the team for the remaining red ball fixtures and will consider the options that are out there but it's a particularly tough market at this stage of the season.

"If there's something that can be done then we’ll explore it but there isn't a long list of available overseas talent," he said.

De Kock is currently the Proteas' stand-in skipper for final two one-day internationals against Sri Lanka, replacing the injured Faf Du Plessis.
