Vikas, a former World Championships bronze-medallist and an Asian Games gold-winner, had given a walkover to Korean Lee Dongyun in the middleweight (75kg) semifinals in Tashkent, Uzbekistan last week.
The reasons for his decision were not known at the time of the forfeiture and Boxing Federation of India (BFI) President Ajay Singh today said there would be an enquiry into the matter.
Vikas was to turn up for the British Lionhearts in a WSB encounter scheduled for May 11. His semifinal bout at the Asian meet was to be held on May 6.
The Haryana-pugilist was conspicuous by his absence in a breakfast hosted by the BFI President for the team, which returned to the country in the wee hours today.
Vikas is among the most decorated boxers in Indian boxing. A two-time Olympian, he became the first Indian to be adjudged the best boxer by the International Boxing Association (AIBA) at its annual gala last year.
Vikas was the middleweight top seed in the Asian meet.
