Sushil had won a bronze in freestyle 66 kg category at the 2006 Doha Asiad.
Sushil, who won a bronze and a silver in 66kg freestyle in 2008 and 2012 Olympics respectively, said that his preparations for Glasgow Commonwealth Games (July-August) and Incheon Asian Games (September-October) has been going on well despite having to shift to higher weight categories due to change in rules.
Due to change in rules by FILA and to accommodate fellow 2012 Olympics medallist Yogeshwar Dutt, Sushil will now contest in 74kg category in Glasgow and 70kg in Incheon.
