Stormers star number eight Duane Vermeulen is due to see a neurosurgeon on Monday after being withdrawn from Saturday's game.
The Springbok international picked up a neck injury on Friday before the game with the Lions, after being named to start and captain the side.
Nizaam Carr started in Vermeulen's place as the Stormers won the South African Conference at Newlands but the condition of Vermeulen ahead of the play-offs will be a real concern for the side's supporters, not to mention the Springboks and Heyneke Meyer.
"Duane suffered a severe spasm in his neck after Friday’s captain’s run. We sent him for an MRI and it showed a bulging disc at a C5 level which is causing the (intense) spasm,” explained Stormers doctor Dr Jason Suter.
“Based on that he was removed from Saturday’s match. In terms of his prognosis, and his management, it’s too early to say at the moment.
“At this stage he has no neurological symptoms, so he has no fall-out that requires urgent intervention or surgery, but the next 24 hours will tell us how we will manage him and how long the expected time for recovery is.
“He will see a neurosurgeon on Monday. We’ve sent on his scans already (to the neurosurgeon) to start looking at what the potential management is going to be."
