The Cheetahs are sweating over the fitness of three key forwards following Saturday's win over the Bulls.

Lock Reniel Hugo appears to have suffered a serious knee injury, while Ox Nche and Uzair Cassiem are also feared to have sustained ligament damage that could sideline them for a few weeks.

The Cheetahs will host the Sunwolves in Bloemfontein this Saturday.
