Amit Phangal in 49 kg category and Gaurav Bidhuri in 56 kg upstaged fancied rivals to enter the quarterfinals but former bronze-medallist and third seed Vikas Krishan in 75 kg category was ousted after a second-round loss in the 19th World Boxing Championships in Hamburg, Germany. While Amit stunned seventh seed Carlos Quipo of Ecuador, Gaurav got the better of Ukrainian Mykola Butsenko in a pre- quarterfinal bout. However, Vikas, a bronze-winner from the 2011 edition, bowed out after being bested by England's Benjamin Whittaker.Also making an early exit was Asian silver-medallist Sumit Sangwan in 91 kg category who lost to Australia's Jason Whateley in a split decision. Amit has a tough contest coming up as he would be taking on second-seeded Uzbek Hasanboy Dusmatov, while Gaurav will face Tunisia's Bilel Mhamdi in his next contest.
