London 2012 gold medal winner lost by split decision
Reigning Olympic champion Katie Taylor is out of the Rio Games.
The London 2012 gold medal winner was facing Mira Potkonen of Finland in her women's lightweight quarter-final, losing by split decision.
Taylor edged the first round with the Bray boxer up on two judges' cards and her opponent deemed to have won it by the third arbiter.

The margin of defeat was incredibly tight on the judges' cards over the four rounds of action:
Judge B had called the fight level but in the end, deemed that Potkonen was the winner with Judge A having adjudged that Taylor should go through.
