The Australian, last defeated Teofimo Lopez to win all the 135 lbs belts, he is now looking for another challenge, which is yet to be confirmed and could be the American Devin Haney.

Kambosos has shown his responsibility and commitment to stay on top of boxing. Recently he has been seen punching the bag through videos on his social networks, in an evident demonstration that he is starting to get in shape for his next commitment, which could be in the month of June.
