Johannesburg - Bulls loose forwards CJ Stander and Dewald Potgieter are in doubt for the last match of the side's Australasian tour.
The Pretoria union said on Saturday that Stander (hip) and Potgieter (AC joint) would undergo scans on Monday after they picked up injuries in the 16-11 loss to the Highlanders in Dunedin on Saturday.
The Bulls, who were second in the overall standings ahead of the weekend matches, face the Chiefs in Hamilton on Friday in the last game of their tour.
