For the lazy amongst you here's the weights anyway:

David Haye weighed 15 stone 7 pounds (217 lbs) and his opponent Tomasz Bonin comes in at 16 stone 7 pounds (231 lbs).

For the light heavyweight title fight Peter Oboh (12 stone 6; 174lbs) held a four pound advantage over opponent Tony Oakey (12 stone 2; 170 lbs).
