The team, consisting five in men's freestyle, six in Greco-Roman and six in female wrestling, is likely to reach Astana on March 15.
In Men's freestyle, all eyes will be on Yogeshwar to book an Olympic berth for India in 65kg category, while at least two out of four others in the fray -- Rahul Aware (57kg), Somveer (86kg), Satyawart Kadiayan (97kg) and Hitender (125kg) -- are also expected to qualify for the Rio Games.
London Olympic bronze medallist Yogeshwar could not fight during the last year's World Championship due to an injury.
In Female wrestling, Phogat sisters -- Vinesh (48kg) and Babita (53kg) -- and Sakshi Malik (58kg) stand a good chance of booking a quota place for the country in their respective weight categories.
