Burger’s neck injury, picked up last weekend against the Cheetahs, couldn’t be properly assessed because he is one of the seven Capetonians currently at the national camp in Durban.
“The chances of Schalk playing against the Sharks are touch-and- go,” said Stormers coach Allister Coetzee.
Duane Vermeulen, pictured, will again take over the captaincy if Burger is rested.
“At this stage we are preparing as if Schalk won’t be playing, but we’ll get a chance to see him when he returns from Durban and then make a call on Wednesday (today),” Coetzee added.
The Stormers face a disruptive week and will only be able to train once on Friday as the Boks are only returning to Cape Town today, while the players have a rest day tomorrow.
While lock Manuel Carizza has been cleared to make a return since last playing at the end of February, Sailosi Tagicakibau is likely to come in on the right wing for Kobus van Wyk, who has been ruled out for three weeks after re-injuring his wrist last weekend.
Hooker Deon Fourie, however, remains a doubt.
