Cape Town - Stormers flyhalf Jean-Luc du Plessis has been ruled out for four to six weeks with a groin injury.
The 22-year-old playmaker underwent scans on Monday, which revealed that he has a bone stress injury to the pubic bone, complicating the recovery from his groin strain.
There were no new injuries sustained in the 41-10 Super Rugby Round 3 victory against the Southern Kings in Port Elizabeth.
The Stormers have a bye in Round 4, before travelling to Singapore to play the Sunwolves on Saturday, March 25 at 12:55 (SA time).
