The Stormers will be without Springbok forward Pieter-Steph du Toit for their Super Rugby opener against the Jaguares on Saturday.
The 25-year old, who finished 2017 in the No 7 jersey for the Springboks, has been battling a back injury in pre-season and has been given some extra time off to fully recover.
Meanwhile, Wilco Louw has recovered from the hip injury he picked up in a warm-up clash against the Bulls in Wellington two weekends ago.
Captain Siya Kolisi, who was left out of that pre-season clash against the Bulls as a precaution, is also fit to start on Saturday.
Coach Robbie Fleck will name his side for the clash on Thursday, while kick-off on Saturday is at 15:05.
