Lions flyhalf Elton Jantjies will be fit to face the Blues at Ellis Park on 14 May.
Jantjies sustained a medial collateral ligament injury of his right knee during the 50-17 loss to the Hurricanes.
Meanwhile, hooker Malcolm Marx and prop Julian Redelinghuys are making steady progress in their recovery and may also return for the Lions' next match.
