Stormers hooker Scarra Ntubeni could be sidelined for two weeks with a calf injury sustained in Saturday's win over the Cheetahs at Newlands.
Ntubeni limped off in the 19th minute of Saturday’s clash and could miss next week’s Sharks fixture in Durban, having initially only been ruled out of this weekend’s meeting with the Lions at Newlands.
Stormers head coach Allistair Coetzee admitted that Ntubeni's injury is a setback.
“It’s a blow, especially in a specialist position like hooker and hopefully he will be available for the Sharks game," he told the Stormers' official website.
"However, his injury has opened the door for one of Mikey Willemse or Neil Rautenbach to put their hands up.”
Meanwhile, Michael Rhodes and Kobus van Wyk are both available for selection against the Lions – along with centre Jaco Taute.
“It’s a headache (a good one of course), as I said last weekend… (but) who do you leave out now that everyone is fit and available?" added Coetzee.
"It’s those decisions we need to make in a tough week with the Springbok training camp on the go, too, with 19 of our players in the camp.”
