Volmink, 24, made his way back this year from a serious shoulder injury in the Vodacom Cup team as coach Johan Ackermann wanted him to work on his conditioning before calling him back to the Super Rugby outfit.
With former Bulls wing Courtnall Skosan failing a concussion test earlier this week after receiving a heavy knock during the disappointing 28-7 loss to the Crusaders last weekend, the six-time capped Volmink could make his long awaited return.
There could also be call-ups for flank Derick Minnie (cheekbone), fullback Coenie van Wyk and hooker Robbie Coetzee (knee), who have just returned from injury.
The lineouts were a source of concern last weekend in the absence of experienced lock Franco van der Merwe. Even though Martin Muller replaced Van der Merwe – who normally calls the lineouts – in the vital No 5 lock position, it was decided that Franco Mostert would call the lineouts last weekend against the Crusaders, but the Lions lost six balls on their own throw.
