The TAB's suspended all but one line of betting on the last round robin game in the Super 14 rugby competition, the Stormers-Bulls clash at Cape Town.
The away fixture for the top of the table Bulls comes after they booked a home semi-final last weekend, and the champions are reported to be considering resting most of their stars for Sunday's match, against their second-placed South African compatriots.
A Stormers win would mean a home semi-final for them, while removing that possibility from the other contenders, including the Hurricanes and the New South Wales Waratahs, who clash on Friday night.
Hurricanes coach Colin Cooper doesn't want to speculate on what may happen in South Africa this weekend, preferring instead to focus on their last do-or-die pool game in Sydney.
Cooper welcomes back centre Conrad Smith from concussion for the crucial Waratahs match, but flanker Victor Vito's still in doubt.
