Right, you know the rules, watch the low blows, if it's a knock-down no messing about, go straight to your corner, and don't come out till called for, are we clear? Touch gloves, let's go.In the red corner: Leon Davidson - Black British champ or Uncle Tom? In the blue corner: Troy Augustus - American powerhouse or naive cash cow?

With an introduction by Harry Derbyshire, Lecturer in English and Drama at the University of Greenwich.
