Saiz was implicated in the Operacion Puerto blood doping scandal in his former role as manager of the Liberty Seguros team, though the UCI insisted they were unable to deny him a licence, as his role in the affair could not be proven.
In a statement, the UCI criticised the "lack of information on the part of the Spanish authoritites" and "the highly confusing general context of Operacion Puerto."
The UCI also insisted it would "take every measure that it thinks necessary to protect the interests of cycling, especially concerning disciplinary procedures against any implicated individuals."
