KickOff.com understands that Dos Santos and office staff members Duan Baker (media) and Anele van Niekerk (marketing) have been released by the Urban Warriors, who are fighting their relegation to the National First Division through the courts following the Tendai Ndoro saga.
Ajax are expected to learn on Monday whether their bid for survival is successful.
"I cannot confirm this," Mekuto told this website when asked about Dos Santos. "I will not lie to you.
"Until it has been confirmed, that will be the case. But at the moment this is just rumours."
The experienced Dos Santos, a former Cape Town Spurs, Kaizer Chiefs and Orlando Pirates coach, has been talent-spotting for Ajax since 2014.
The Urban Warriors earlier this week confirmed the departure of Ndoro following the expiry of his six-month deal in the Mother City.
