Lucas 'Big Daddy' Browne has faced some big challenges in his boxing career thus far.
Yet, he has conquered every single one, currently with a perfect professional record of 25-0, with eyes for a perfect 26 on March 25 when he faces Englishman Dillian Whyte.
However, Browne's biggest challenge may have come in the form of Ian 'Dicko' Dickson, Marcia Hines and Mark Holden.
When Browne joined Triple M's The Rush Hour with MG, it was revealed he not only auditioned for the show in 2004 but made the Top 50 contestants, narrowly missing selection to advance to the Top 24.
It was also revealed, Brown was a former junior rugby league star for the Parramatta Eels during the mid-90's and he once fought current UFC Light Heavyweight Champion Daniel Cormier in an MMA fight in 2010.
