Another former Springbok player, Os du Randt, who was with him at the gathering, also wrestled with the gunmen despite being pepper-sprayed in his eyes.
Drotske's former teammate and loosehead prop for the Springboks Jacobus Petrus "Os" du Randt, was apparently also at the scene.
Naka Drotske, a member of South Africa's 1995 Rugby World Cup winning squad, is in critical condition in hospital after being shot during a robbery in Pretoria. Drotske underwent surgery immediately upon arrival at the hospital and will require a further operation on an injured arm.
Police, who combed the property Friday seeking forensic evidence, said two men were being questioned in connection with the incident, but had not been arrested.
Drotske played for and coached the Bloemfontein-based Free State Cheetahs in the domestic Currie Cup and southern hemisphere Super Rugby competitions.
Meanwhile, News24 reports that police say two men have been taken in for questioning in connection with the attack.
Ex-Springbok Shot Three Times During Robbery
After being rushed to hospital, Drotske was initially listed as "critical" but a hospital spokesperson confirmed to AFP Saturday that he was now "stable".
It was the first major sporting event to take place in the country following the end of apartheid.
Drotske featured at hooker during the Springboks' win over Samoa during that tournament, and started for the side throughout the team's 1999 World Cup campaign as they finished third in the tournament.
Drotske won 26 caps for South Africa, scoring three tries.
"Naka jumped up and stormed them, and then they shot him three times, and then they luckily fled".
He later coached the Cheetahs before pursuing a business career.
