Etzebeth back as Sharks opt for consistency
Springbok lock Eben Etzebeth is back from injury and will start for the Sharks against Edinburgh in Durban on Saturday.
It's the only change to the Sharks team that thrashed Zebre 47-3 at Kings Park last weekend.
Etzebeth replaces Corne Rahl who moves to the bench in place of Gerbrandt Grobler. The other change is on the bench where replacement hooker Dan Jooste comes in for Kerron van Vuuren.
Hooker Bongi Mbonambi, analysing Edinburgh and the team they will put out for this match, expects a challenging encounter from the Scots.
"It's a quarter-final, they will bring their best team, hoping to advance to the semi-finals," Mbonambi said.
"We're preparing for their best team."
Sharks team:
15 Aphelele Fassi, 14 Werner Kok, 13 Lukhanyo Am (captain), 12 Ethan Hooker, 11 Makazole Mapimpi, 10 Siya Masuku, 9 Jaden Hendrikse, 8 Phepsi Buthelezi, 7 Vincent Tshituka, 6 James Venter, 5 Emile van Heerden, 4 Eben Etzebeth, 3 Vincent Koch, 2 Bongi Mbonambi, 1 Ox Nche

Bulls make mass changes for Northampton Saints semi-final
Bulls director of rugby Jake White has gambled by making mass changes to his side for Saturday's Champions Cup semi-final against Northampton Saints at Franklin's Gardens.
White made no fewer than 14 changes to the starting XV that thrashed French club Lyon 59-19 in Pretoria last weekend.
Winger Sebastian de Klerk is the only survivor in the starting XV, with flanker Nizaam Carr named to captain the Bulls.
These "second string" selections confirm White's intention to rather prioritise the Bulls' URC campaign.
Bulls team:
15 Devon Williams, 14 Sebastian de Klerk, 13 Henry Immelman, 12 Harold Vorster, 11 Stravino Jacobs, 10 Chris Smith, 9 Zak Burger, 8 Cameron Hanekom, 7 Mpilo Gumede, 6 Nizaam Carr (captain), 5 JF van Heerden, 4 Janko Swanepoel, 3 Mornay Smith, 2 Akker van der Merwe, 1 Simphiwe Matanzima
Substitutes: 16 Jan-Hendrik Wessels, 17 Dylan Smith, 18 Francois Klopper, 19 Merwe Olivier, 20 Reinhardt Ludwig, 21 Kaegan Johannes, 22 Jaco van der Walt, 23 Cornal Hendricks
