An ankle injury to utility back and Springbok Frans Steyn has ruled him out of the Sharks side to face defending Super 14 champions the Crusaders in Durban on Saturday.
The match, which pits the unbeaten Sharks against the defending champs, is the pick of the weekend's Super 14 games but Steyn could be out of action for three to four weeks, making him a risk for the Sharks' departure to Australia and New Zealand for their tour at the end of March.
Coach Dick Muir reported a clean bill of health otherwise.
"Last weekend's bye did us a lot of good. Most of the sore bodies have now had a good rest," Muir told Beeld newspaper.
Muir is expected to return Springboks John Smit and Butch James, who were rested from the last game for the clash, and has hinted that veteran Bok lock Johan Ackermann could also get a run.
Muir said the Sharks had taken note of the Crusaders big win over the Cheetahs last weekend.
"I must confess that I didn't expect them to win so easily," Muir said. "It just shows they (Crusaders) have not won the series so many times for nothing. They have a clever coaching team under Robbie Deans."
