The Southern Kings recalled an Argentine and French player from their touring squad in New Zealand on Wednesday as the South African Rugby Union investigated the Super 15 newcomers for breaking its rules on foreign players.
The Kings said Tomas Leonardi and Virgile Lancome will return to Port Elizabeth and be replaced by two South Africans for the four-game tour of Australasia.
Kings president Cheeky Watson also travelled to New Zealand to talk to the players after the team was threatened with a caution, fine, suspension or even expulsion by SARU in its debut Super Rugby season if found guilty of fielding too many foreigners in a game against the Chiefs last week.
But Super Rugby chief Greg Peters said on Twitter that SARU did not have the authority to suspend or expel the Kings, as that would affect the whole three-country tournament and only a South African rule had allegedly been broken.
It leaves the Kings facing a warning or fine of up to 1 million rand ($108,000).
