Stormers

 Both sides are unbeaten heading into the clash.

From the side that beat the Bulls in Hamilton last weekend, Kane Hames and Atu Moli are promoted from the bench to start alongside veteran hooker Hika Elliot in the front row. Taranaki loose-forward Lachlan Boshier returns to the 23 to replace the injured Sam Cane in jersey 7.

There are two changes to the backline with explosive Counties Manukau back Toni Pulu returning from a hamstring strain to start on the right wing and fan favourite Stephen Donald moving from the bench to claim jersey 12.

The Chiefs, who outscored the South Africans by eight tries to three, now travel home to meet the top-ranked Hurricanes in Wellington next weekend. The Lions host the Highlanders in the other semi in Johannesburg.

The Chiefs built a 20-point lead by halftime at Newlands as they caught out the hosts with pace and quick movement of the ball.

Leading 2015 Rugby World Cup points scorer Nicolas Sanchez fluffed two relatively simple chances to add to his early penalty against the South African visitors.

The fly-half missed the conversion of a try by centre Jeronimo de la Fuente at the end of a first half in which all 21 points were scored before a large crowd at Estadio Jose Amalfitani in Buenos Aires.
