Paulie Malignaggi
After discussions to fight Paulie Malignaggi on the Saul Alvarez-Ryan Rhodes undercard fell through, Zavec traveled to Biloxi, Mississippi to face former WBC light-welterweight champion Andre Berto on HBO on September 3, 2011. Despite being a 4-to-1 underdog coming into the fight, Zavec proved competitive; trading clean punches with Berto and earning praise from HBO's Roy Jones Jr. In the fifth round, a number of cuts opened on Zavec's face, which resulted in Zavec's corner waiving the fight off before the sixth round. The loss ended Zavec's reign as IBF welterweight champion.
