George Kambosos Jr. says he's endured eight weeks of torture to ensure he's in "ultimate shape" for his looming unification blockbuster with American Devin Haney.
Kambosos (20-0, 10KO) will place his WBA, IBF and WBO belts on the line in pursuit of Haney's WBC strap in front of 55,000 fans at Melbourne's Marvel Stadium on June 5.
