Vikas would be India's 75kg contender in the event, replacing Olympic and World Championships bronze-medallist Vijender who has turned professional.
The 23-year-old pugilist returned from Sheffield, UK, yesterday after the 14-day training stint, said a media release.
Krishan, who bagged a bronze in last year's Asian Games in Incheon, South Korea, spent time at the English Institute of Sports in Sheffield, Yorkshire, preparing with Britain's boxing team ahead of taking part in the Asian Championship in Bangkok, beginning on August 26,.
Krishan is set to kick off his quest to qualify for next year's Rio Olympics in the 75 kg category at the Asian Boxing Championship. He is now busy training at the National Institute of Sports (NIS), Patiala.
The southpaw has been competing in the 75 kg category, having moved up from the 69 kg category in which he reached the pre-quarterfinal stage of the 2012 London Olympics.
Krishan said that it was, perhaps, the best way to prepare for what he termed as a very important tournament with an eye on the Olympics.
"Sparring with some of the top boxers in the world is always helpful and allows you to make a good assessment of your own preparations, technique and mind-set," said Krishan.
