Belgrade: Indian boxers Nishant Dev (71kg) and Sanjeet (92kg) made the quarterfinals following impressive victories but three others bowed out of the AIBA Men's World Championships after losing their last-16 stage bouts here on Monday.
Nishant defeated Mexico's Marco Alvarez Verde 3-2 in a late night bout on Sunday to set up a clash with Russia's Vadim Musaev.
Sanjeet, a quarterfinalist from the previous edition, got the better of Georgia's Giorgi Tchigladze 4-1 to enter the last eight stage for a second successive time.
He will face Italy's Aziz Abbes Mouhiidine.

However, Rohit Mor (57kg) went down to Kazakhstan's Serik Temirzhanov 1-4. Akash Sangwan (67kg) too lost 0-5 to Cuba's former world youth champion Kevin Brown Bazain in a fight that left both the boxers with bloodied faces.
Also exiting the tournament was Sumit Kundu (75kg), who fought valiantly against another Cuban in Yoenlis Hernandez but lost 0-5.
Mor gave a good account of himself by fighting hard and taking his chances against the technically sound Kazakh, who was especially terrific in the opening round with his attacks.
Mor troubled him with his own brand of aggressive tactics, which included some good footwork but he struggled to connect.
Sangwan was equally gritty but lacked in footwork and was perhaps a bit too worked up during the contest.
