The ministry the decision has been taken so that athletes need not wait for one full year after their medal-winning performances at the Olympic Games.
The medal winners in individual events who have already not been conferred with Rajiv Gandhi Khel Ratna in the past will be considered for the highest sporting honour.
"Medal winners in team events, who have played stellar roles in the medal won by the team for the country in Rio Olympics 2016 such as number of goals scored, number of goals saved etc., and who have already not been conferred with Arjuna Award in the past will be considered for Arjuna Awards," the Ministry said.
