Sumit (60kg), Ashu (67kg), Vikas (77kg), Sunil Kumar (87kg), Nitesh (97kg) and Naveen (130kg) lost their bouts, with the focus now shifting to freestyle.

Sumit lost his 60kg opening-round bout to Romanian opponent Razvan Arnaut on technical superiority 10-0, while in 67kg, Ashu overcame his Norwegian rival Haavard Joergensen 5-4, before losing 10-0 on technical superiority to seventh-ranked Hungarian Krisztina Vancza.

In 77kg category, Vikas got the better of Riccardo Abbrescia of Italy before going down in the pre-quarterfinal bout to Georgia's Luri Lomadze 8-0 on technical superiority.

Lomadze jumped out to a big lead using an arm throw for two points. He then got behind Vikas to nail a four-point throw. Lomadze then effected a takedown that ended the contest with 25 seconds to spare in the first period.

In the 87kg category, Sunil Kumar overcame the challenge from Jose Andres Vargas 3-1 before losing to Azerbaijan's Rafig Huseynov 4-3 in the pre-quarters.

In fact, Olympic bronze medallist Rafig advanced to the quarterfinals by the slimmest of margins, overcoming a 3-1 deficit in the final seconds for an improbable win.

With time running out, Rafig got in on a body lock and forced Kumar over the edge for a step-out. But the Indian was assessed a one-point penalty for fleeing, giving Rafig a 3-3 win on criteria. An unsuccessful challenge added the final point.

In the 97kg category, Nitesh got eliminated in the qualification round itself, losing to Poland's Tadeusz Michalik, who effected a victory by fall.

Naveen, in 130kg category, too bowed out in the qualification round losing to Austria's Daniel Gastl on points.
