Duane Vermeulen will captain the Bulls this weekend when they face the Brumbies on Friday after Handre Pollard was ruled out of the tour with a calf strain forcing the regular captain and flyhalf to return home.
In Pollards absence, Manie Libbok will wear the No 10 jersey with JT Jackson providing cover on the bench.
The Bulls are otherwise unchanged from their 32-17 victory over the Rebels last week and if they are to stand a chance of winning the South African conference they will need a similar result in Canberra before they head to New Zealand to face the Blues and Highlanders.
Bulls – 15 Warrick Gelant, 14 Cornal Hendricks, 13 Johnny Kotze, 12 Burger Odendaal, 11 Rosko Specman, 10 Handré Pollard, 9 André Warner, 8 Duane Vermeulen (c), 7 Hanro Liebenberg, 6 Paul Schoeman, 5 RG Snyman, 4 Jason Jenkins, 3 Trevor Nyakane, 2 Schalk Brits, 1 Lizo Gqoboka.
Subs: 16 Jaco Visagie, 17 Simphiwe Matanzima, 18 Wiehahn Herbst, 19 Jannes Kirsten, 20 Marco van Staden, 21 Embrose Papier, 22 Manie Libbok, Divan Rossouw.
