Fit-again Springbok centre Juan de Jongh has flown to Australia to bolster the injury-hit Stormers after two successive Super Rugby defeats.
De Jongh will replace injured lock De Kock Steenkamp, who has a groin injury and joins five first choice players on the sidelines after a bruising first four matches of the season.
Coach Allister Coetzee says De Jongh is over a knee problem and could line-up against the ACT Brumbies in Canberra on Saturday.
Springbok captain Jean de Villiers, who suffered a shoulder injury against the Waikato Chiefs last Friday, has been passed fit.
Meanwhile, the Bulls have reinforced their squad with former captain Dewald Potgieter.
Following successful negotiations with his Japanese club, Yamaha Jubilo, Potgieter will be available to the Bulls for the rest of the regular Super Rugby season.
