England's Buttler among players retained in SA20

England's Jos Buttler, Will Jacks and Jonny Bairstow are among the players retained by franchises in South Africa's SA20 competition, prior to the league's draft.

Sides are allowed to hold on to a maximum of six players, three domestic and three international, plus an extra "wildcard" signing, with the remainder of their squads from last season released into the draft on 9 September.

The English trio have been retained by Durban's Super Giants, Pretoria Capitals and Sunrisers Eastern Cape respectively.

Fellow internationals James Vince and Richard Gleeson have also been kept on by Joburg Super Kings.

Sunil Narine, Rashid Khan and Andre Russell, all veterans of the franchise circuit, are among the overseas players signed up by franchises, while home stars Heinrich Klaasen, Kagiso Rabada and Marco Jansen have also been retained.

However fellow South African internationals Aiden Markram, Lungi Ngidi, Wiaan Mulder, Quinton de Kock, Anrich Nortje and Keshav Maharaj, along with recent caps Dewald Brevis and Kwena Maphaka, have all been released.

Champions MI Cape Town are the only franchise to use all six of their player slots, with each retention reducing the amount of money a side has to spend at the draft.

The SA20's fourth season will start on Boxing Day and run through to a final on 25 January.
