The Springbok Sevens have called up Steven Hunt, Kwagga Smith and Rosco Speckman as injury cover for Stephan Dippenaar, Jamba Ulengo and Frankie Horne.
The South Africans will be in action over the weekend in the Cell C Nelson Mandela Bay Sevens in Port Elizabeth.
Dippenaar was ruled out of action with a hamstring injury, while Ulengo is doubtful because of a foot injury and Horne suffered a blow to the leg this past weekend in Dubai where the Springbok Sevens finished as runners-up to Fiji in Round 2 of the HSBC Sevens World Series.
Hunt, Smith and Speckman were all in action in Dubai where they helped the SA Sevens Academy team defend their Dubai Invitational title for a fourth successive time.
They arrived in Port Elizabeth on Tuesday and joined the squad for their first training session on the B-field of the Nelson Mandela Bay Stadium late in the afternoon.
Neil Powell, the Springbok Sevens coach, will announce his 12-man squad at a media conference on Thursday afternoon.
Earlier today, Springbok Sevens captain Kyle Brown joined the other 15 captains at the International Captains Signing Session at Green Acres Shopping Centre.
This popular tournament promotional event was again well supported by the local crowd.
The team attended a corporate breakfast in the morning and then headed straight to the Virgin Active gymnasium for an hour-long workout session.
