Adriaan Strauss, Jan Serfontein and Handré Pollard will be considered for the Vodacom Bulls' match against the Sharks in Durban on Saturday.
All three Springbok players will travel with the squad, along with Lappies Labuschagne, who has recovered from a shoulder injury that saw him miss the games against the Crusaders, Lions and Reds.
Strauss was rested for the Reds match per Saru's agreement, while Serfontein last played against the Force and Pollard against the Crusaders.
Akona Ndungane has also recovered from a broken hand, while Victor Matfield (knee, two to three weeks), Travis Ismaiel (ribs, 20 April) and William Small-Smith (foot, 20 April) will return before month's end.
