It seems that the Stormers will have to make do without full-back Jaco Taute who suffered a potentially season-ending knee injury against the Cheetahs on Saturday.
Taute was forced off the field in the 30th minute after he tore knee ligaments from going over Willie le Roux's leg in a tackle.
"We are waiting on official confirmation from the doctor," said coach Allister Coetzee of Taute's freakish injury. "But Jaco could be out for the rest of the season with a damaged ACL."
Tiaan Liebenberg, Eben Etzebeth, Peter Grant and Schalk Burger are other key players already missing from the Stormers' team sheet.
On other injuries, Coetzee added: "Siya Kolisi suffered a slight ankle strain, but he will train this week and we will have to see about Elton Jantjies who twisted his knee a bit. Elton was in a bit of pain after the match, but we will know more on Monday."
Forwards Don Armand (intercostal rib muscle injury) and Rynhardt Elstadt (shoulder) will also be assessed on Monday, after missing the Cheetahs match, but winger Gerhard van den Heever (knee) will not be back this coming week.
Hooker Scarra Ntubeni (shoulder) will take a full part in training this week, but won't be considered for selection as yet and neither will lock Etzebeth (ankle) and wing Bryan Habana (knee), who are still undergoing treatment on their respective injuries.
