Taekwondo is only allowed 4 fighters at the 2012 games and are allowed to nominate their weight categories they announced that they would be womens -57 and -67 and mens -68 and -80. At -80 the two rivals are obviously Cook and Muhammad. They have fought twice and are 1-1.
Both fighters entered the European Championships - Cook at -80 but Muhammad was force up to the -87 as GB can only enter one per division. BBC fail to mention that Muhammad then won Gold at the higher weight category. There is no under 87 weight category at the Olympics it is simply over 80. The world rankings are therefore also a bit confusing as there are two, one is for the WTF under their normal weights and then there are the Olympic rankings which are combined weight groups rankings - i.e. one is -80 and -74 some of the points go back to the events from 2010.
So the decision comes down to two fighters at -80 Cook or Muhammad - they are both European Champions and are 1-1 however obviously Cook is higher ranked in the World
