New Delhi: Two-time Olympic-medallist Sushil Kumar has opted out of the World Championships after sustaining a shoulder injury, thereby taking the sheen out of the upcoming selection trials, slated for July 6-7 in New Delhi.

The World championships, scheduled to be held in Las Vegas from September 7-12, will also be the first qualification tournament for the 2016 Rio Olympics. "Yes, I have sustained an injury to my right shoulder while practising. So I would not be able to take part in the upcoming selection trials. So, automatically that rules me out of the first qualifying event for next year's Rio Olympic Games," Sushil said.
