Willemse will consider players from the Blue Bulls if required for his squad to face the Lions in Rustenburg on Saturday, 30 May. He will also be able to pick players from the Griquas, Griffons, Valke and Pumas.
The Griquas, coached by former Springbok Dawie Theron, beat Free State 30-25 in Kimberely to book their ticket in the last four. Theron, who will assist Willemse with the coaching against the Lions, now has to prepare his side to face the Sharks in Durban.
The Lions face the Sharks in their third tour match.
