UCBSA said it had written to Indian authorities to "clarify" the matter, the Pretoria News reported on Tuesday.
Former South African cricket captain Hansie Cronje was banned for life from cricket by the UCBSA in 2000, a decision which was later endorsed by the game's governing body, the International Cricket Council (ICC), after he admitted to taking money to fix matches involving South Africa in India.
Cronje sparked the match-fixing scandal after Indian officials said they had tape recordings of him talking with an Indian bookmaker during the team's tour of the subcontinent.
Gibbs and Boje were also implicated in the scandal.
"We wrote to the BCCI (Board of Control for Cricket in India) in March and asked them to clarify the issue," UCBSA spokesman Gerald de Kock said.
"They replied to us that they did not think there would be a problem," he said. "We wrote them another letter two weeks ago saying we required something more definite and we are waiting to hear from them."
De Kock refused to spell out what the UCBSA's stand would be if the Indian police decided to grill the pair, saying: "We will cross that bridge when it comes."
The India tour was meant to be a full one with Tests and One-day series but has been now downgraded to a series of Limited Overs matches.
