Based on my search, there's only one player named Andres Guibert in NBA history:

Andrés Guibert Sangerton, a Cuban-Puerto Rican former center/power forward.

Here's an interesting fact about him:

Defection during a competition: Guibert made headlines in 1993 when he defected from the Cuban delegation at the Central American and Caribbean Games held in Puerto Rico. This act marked a turning point in his career, allowing him to pursue professional basketball opportunities outside of Cuba.
