Olympic boxing: Adams guarantees herself medal

GB's Nicola Adams guarantees herself at least a bronze with a convincing win in her Olympic fight at the ExCeL arena.

Adams outclasses Stoyka Petrova of Bulgaria 16-7 in the women's fly (51kg) quarter-finals and will definitely walk away with a bronze having only fought once, after she received a bye in her first round.
