The Sharks have suffered a hefty blow as it has been revealed that Springbok hard man Willem Alberts will be out for four more weeks of Super Rugby.
The Sharks are already without captain Keegan Daniel and centre Tim Whitehead but now Alberts needs an operation.
Alberts missed the Super Rugby warm ups as he has been in rehab for his shoulder but he is now expected to miss another four weeks.
The Springbok will have an "small" operation on his shoulder on Tuesday.
The Sharks play the Cheetahs, Stormers, Kings and Brumbies over the next four weeks and if all goes well Alberts could return to face the Rebels in Round 6.
Meanwhile assistant coach Hugh Reece-Edwards says that aside from the injuries picked up the Sharks are happy with their pre-season preparation.
"The game against the Pumas was the hit-out and physicality we needed after what we had against the Leopards which wasn't a really physical match," said Reece-Edwards on the Sharks site.
"That physicality was right up there with anything we'll experience in Super Rugby this season."
"We feel we've gotten out what we wanted from the two games, although had we sustained no injuries, we'd be happier. "
"We would have had no injuries had we had no games, but you need the hit-outs, certainly this last game we got the physicality we needed.
"So from that point of view our physical preparation has been good and we're happy with that."
