South Africa duo Pieter-Steph du Toit and Elton Jantjies look likely to be involved in Saturday's first Test against Ireland, despite earlier updates suggesting they would miss the series.
The Springboks take on Ireland in three Tests, with the first taking place in Cape Town this weekend.
Late last month, fly-half Jantjies had to undergo surgery on a broken finger, while prop Du Toit's torn hamstring meant he was replaced by Franco Mostert on May 31.
Both men looked set to miss Ireland's tour, but an update on Monday provided positive news on the pair.
"Elton will take some part in some skills training, but he won't take contact just yet," said team doctor Konrad von Hagen on Jantjies, who will wear a custom-made brace to protect his finger.
"We'll see how he progresses in the week and his return to action will be done in consultation with the Emirates Lions medical team. Pieter-Steph has been recovering well and he has been cleared to take part in our training sessions from Monday."
Meanwhile, prop Trevor Nyakane (shoulder) and centre Lionel Mapoe (back) have been passed fit, but Jan Serfontein has fractured his wrist and will miss four months of action.
