by Brendan Bradford – Newly installed South African coach Neil Powell has named an experienced side ahead of the Gold Coast Sevens this weekend. South Africa face England, France and Spain in Group B in what will be the former BlitzBokke captain’s first tournament as head coach after taking over from Paul Treu who resigned in August. Injuries have ruled out experienced scrumhalf Branco du Preez and winger Seabelo Senatla with Sampie Mastriet and Mark Richards joining the squad. Twenty-three year old Mastriet turned out for South Africa at the Rugby World Cup Sevens in June and made a try-scoring Super Rugby debut for the Bulls against the Western Force in Round Three.
