A total of 49 foreign players will be drafted during the session for the eight-franchise league, which is slated to run from October to December. Seven players have been directly recruited by the teams.
"When the drafts came up, the first name that caught our attention was that of Chopra," former England goalkeeper David James, marquee player and manager of the Kerala team, told reporters.
"We immediately decided to have him and are happy to have him in this team."
Chopra, who has also played for a host of other Premier League clubs, was the only English player in the draft, which was held at a Mumbai hotel overlooking the Arabian Sea.
Former Manchester United midfielder Bojan Djordjic has joined other marquee names such as former Juventus striker David Trezeguet and former Arsenal winger Freddie Ljungberg in the first season of the football league.
Strict rules apply to player rosters, with each team required to have one marquee player, seven foreigners and 14 Indians, four of whom must be from the city in which the franchise is based.
