British and Irish Lions

World Cup-winning heroes Fourie du Preez and Jaque Fourie have been named in the South African squad for the three remaining Tri Nations matches and the forthcoming clash with Argentina on August 9.

Scrum-half du Preez and centre Fourie both started October's win over England in the Rugby World Cup Final in Paris but have since spent lengthy periods on the sidelines due to injury.

After missing the previous six international fixtures, both players returned to Currie Cup action earlier this month, with Springbok head coach Peter de Villiers seeing enough to include them in a 30-man squad for the next four fixtures.

Free State Cheetahs wing Jongi Nowke has also been called up to the full squad having been part of the initial expanded training squad ahead of the away leg of this year's Tri Nations.

Springbok skipper John Smit misses out, however, as a result of the groin injury suffered during the 19-8 defeat to New Zealand in Wellington on July 12.

The Springboks assemble on Wednesday morning in Pretoria where they will stay until Sunday, before transferring to Johannesburg to continue with their preparations for the Mandela Tribute Test against Argentina in just under three weeks time.

Lions skipper Sam Warburton says the lessons he and his Welsh colleagues learnt in Australia last summer will stand them in good stead for their return visit with Britain and Ireland's elite next month.

Tom Youngs has enjoyed a remarkable rise to the top of the British & Irish game but he won't be resting on his laurels ahead of his first Lions adventure.
