Panaji: The unbeaten run of star Indian boxer Vijender Singh in the professional circuit ended on Friday night after he was defeated by his Russian opponent Artysh Lopsan in the 'Battle on Ship' here.

Vijender, a bronze medallist at the 2008 Beijing Olympic Games, who turned professional in 2015 had entered the bout with a 12-0 record.

In the opening round, Vijender was cautious in his approach as the Russian outplayed the Haryana boxer and used his height to perfection.

The Russian, who was fighting his seventh bout, outpunched Vijender on the rooftop of the 'Majestic Pride Casino' ship on the waters of the Mandovi River, which resulted in a heartbreak for the partisan crowd.

The referee, after one minute and nine seconds in the fifth round, declared the Russian as the winner as the eight-round bout ended in a knockout.

In the second round, the 26-year-old Lopsan gave an exhibition of his class during and matched Vijender's oodles of experience. He had better exchanges and made optimum use of his punches -- hooks and straight punches -- and tired the Haryana boxer.

The Indian continued to face stiff competition as the 6 feet four inches tall Russian managed to squeeze every ounce of his opponent's energy.

Vijender was visibly troubled and also looked tired in the next two rounds as he was continuously punched by the Russian, who was a tad better on the given day.
