Cape Town - The Lions are sweating over the availability of skipper Warren Whiteley ahead of their Super Rugby semi-final against the Highlanders in Johannesburg on Saturday (15:00 kick-off).
According to Netwerk24, Whiteley is struggling with a calf injury and only did light training with the team on Monday.
There is also doubt over reserve scrumhalf Ross Cronje, who injured his ankle while scoring a try against the Crusaders last weekend.
A final decision regarding both players’ availability will be made on Thursday.
Meanwhile, the Lions also confirmed that flank Robert Kruger had surgery last week for an ankle fracture he sustained against the Jaguares on July 16.
He will be out of action for at least three months.
Coach Johan Ackermann on Tuesday named a 27-man squad for Saturday's game, with the official team announcement to take place on Thursday.
Dillon Smit has been drafted in as cover in case Cronje fails his fitness test.
Lions’ 27-man squad:
Dylan Smith, Corne Fourie, Julian Redelinghuys, Jacques van Rooyen, Armand “Akker” van der Merwe, Malcolm Marx, Lourens Erasmus, Franco Mostert, Andries Ferreira, Ruan Ackermann, Warwick Tecklenberg, Warren Whiteley, Jaco Kriel, Cyle Brink, Steph de Witt
Faf de Klerk, Ross Cronje, Dillon Smit, Elton Jantjies, Jaco van der Walt, Courtnall Skosan, Ruan Combrinck, Sylvian Mahuza, Howard Mnisi, Rohan Janse van Rensburg, Lionel Mapoe, Andries Coetzee
