Former world crusierweight champion Steve Cunningham has endured many battles in the ring, but everything has been insignificant in comparison to having a daughter who needed a heart transplant.

Here, Steve tells his incredible joinery, from the streets of Philadelphia to the Navy, a pro career that started in the middle of nowhere, to some of the biggest fights in cruiserweight history against the likes of Marco Huck, Tomasz Adamek, Krystof Wlodarcyzk, Guillermo Jones and a move up in weight that would later see him fight – and drop – Tyson Fury and draw with Antonio Tarver.

Cunningham went to his opponent's backyard many times, and this is his life on the front line, and behind enemy lines.
