Injuries and national call-ups will see WP fielding a weakened pack of forwards this Saturday.
Flank Rynhardt Elstadt has been ruled out for three weeks with a rib injury. Elstadt sustained the injury in the game against the Cheetahs last week.
WP are already without Siya Kolisi, who sustained a season-ending injury recently. Several of their first choice players are also currently with Boks, including No 8 Duane Vermeulen and prop Frans Malherbe. The latter was called up to the Bok squad on Tuesday.
Wing Ederies Arendse has also been sidelined for six weeks with a shoulder injury.
The only piece of good news for WP is that fullback Joe Pietersen and flank Tyrone Holmes will be making their respective returns from injury this weekend.
