Montgomery is in line to face Ireland and Wales in June

Montgomery is now set to face Ireland on 12 and 19 June and then adopted homeland Wales on 26 June, despite breaking a bone in his hand on Friday.

"He has fractured a small bone in his hand, but that sort of injury can heal within two weeks," White said.

"This means he should be available, but we have a contingency plan."

White revealed that Gaffie du Toit was on standby should Montgomery not recover in time, as the Stormers player can also slot in at either fly-half or full-back.

Montgomery damaged his hand in the 56-39 loss in Leinster that ended the Dragons' Celtic League title hope.

White added that no positions have been finalised for the 22-member squad to play Ireland in Bloemfontein on 12 June.

South Africa squad: Eddie Andrews (Western Province); De Wet Barry (Western Province); Bakkies Botha (Blue Bulls); Schalk Burger (Western Province); Bolla Conradie (Western Province); Quinton Davids (Western Province); Fourie du Preez (Blue Bulls); Os du Randt (Free State); Jaque Fourie (Lions), Marius Joubert (Western Province); Wayne Julies (Free State); Victor Matfield (Blue Bulls); Percy Montgomery (Dragons); Faan Rautenbach (Lions); Brent Russel (Sharks); Hanyani Shimange (Free State); John Smit (Sharks); Juan Smith (Free State); Jaco van der Westhuizen (Leicester); Joe van Niekerk (Western Province); Pedrie Wannenburg (Blue Bulls); Ashwin Willemse (Lions).
