Sharks scrum-half Rory Kockott will be unavailable fro two weeks after suffering an ankle injury in his side's Currie Cup win over the Boland Cavaliers in Durban on Friday.
The Sharks will face the Blue Bulls in Pretoria on Saturday and the Falcons in Brakpan a week later. Coach John Plumtree will have to decided between Charl McLeod and Scott Mathie as Kockott's replacement in the number nine jersey.
"Rory has a soft tissue injury. Charl (McLeod) showed some nice touches, but we also have Scott Mathie playing again so we have an interesting choice to make." Plumtree told the Mercury newspaper.
Plumtree will also have to assign the Kockott's kicking duties. Monty Dumond took over from Kockott against Boland, but he could be replaced at fly-half by the returning Brad Barritt. The other alternative available is to shift Barritt to centre to accommodate Dumond - who is a recognised goal kicker.
