[2] After discussions to fight Paulie Malignaggi on the Canelo Álvarez vs. Ryan Rhodes undercard fell through,[3] Zaveck traveled to Biloxi, Mississippi to face Andre Berto who had just lost the WBC welterweight title to Victor Ortiz.

Zaveck expressed the hope that a victory in his us debut would boost his career saying that "A win over someone like Berto will elevate me to a whole new level.
