Shiva (56kg), who became only the third Indian ever to clinch a medal at the mega-event after Vijender Singh (2009) and Vikas Krishan (2011), went down to Belarus' Dzmitry Asanau despite a dominating performance.
"We were expecting this bout to go our way. Shiva fought very well and it is unfortunate that he lost this bout," national coach Gurbax Singh Sandhu told PTI.
The 21-year-old from Assam, the only one from the six-member contingent to be left in reckoning for the Olympic berth, was on the offensive from the very first bell, daring his rival with an open guard.
The 19-year-old Asanau, a European Games silver-medallist, continued his defensive approach in the second round and did not come on the front foot even once. However, the approach found favour with judges yet again and he nosed ahead 2-0.
In the final three minutes, Shiva attacked with all his might and put Asanau under pressure with his aggressive approach.
However, Shiva aggression could not trump Asanau's defensive tactics and the judges unanimously awarded the bout to the Belarussian.
