The Sharks have suffered a blow after centre Paul Jordaan was ruled out of this weekend's Currie Cup clash with Western Province due to concussion.
Jordaan suffered concussion when the Sharks were beaten 22-15 by Griquas at GWK Park in Kimberley last week. He also has a facial injury.
Meanwhile, former WP back Tim Whitehead is expected to return after being out since missing the Super Rugby final due to a broken hand.
"Paul won't be fit, but on the positive front we've got a few players who will return in the next couple of weeks," Sharks assistant coach Hugh Reece-Edwards said on Tuesday.
"But we're hoping Tim Whitehead will be available this week, and if that happens, it's a case of lose one player and get one back, which is fantastic from that point of view.
"Pieter-Steph [du Toit] is two or three weeks off, and Kyle Cooper is a couple of weeks off, so the guys are slowly returning.
"We've got a very small squad for the Currie Cup, which is around 26, so when you pick up injuries you don't have a lot to work with, especially if the players are from the same position."
