I don't understand. I assume they start out with 0 points but that totally diminishes any chance of that fighter winning the tournament. Still it's a phenomenal opportunity for that fighter because they get an instant title shot against Ward.
Replacement takes over with Zero points. Not a big deal though. If they win both fights they are in the finals. Even one by KO may be enough.
One loss means your not out. In theory, Kessler, Dirrell have lost also. If for example Bika won the next two fights, one by stoppage etc he would be through. Froch could lose and Bika win by KO, he's then above Froch. Two losses and a win without KO and your probably done.
