Ireland's best gold medal hope Michael Conlan is sensationally out of the Olympics after one of the most twisted judging decisions in recent history.
Russia's Vladimir Nikitin was the victor after all three judges scored the fight 29-28.

Second round
Conlan's right hands were finding their range but the Russian was getting through with uppercuts. Conlan had to get treatment to an old cut that opened up during the round. As did his opponent.
Luckily, sense was prevailing...
