The Duleep Trophy is set to return to its traditional zonal from next year after the state units gave a thumbs down to the four-team concept introduced this season. The red-ball event featured four teams -- India A, India B, India C, India D. India A beat India C to win the competition earlier this month. Usually, six teams from as many zones -- central, east, west, north, south and north east -- take part in the tournament, providing more opportunities to the players from their respective zones. "The state units felt the format used this season did not give a fair representation to the players from their respective zones. The traditional zonal format gives players more opportunities zone wise and that is what was conveyed in the AGM today," a state unit official told PTI after the BCCI AGM in Bengaluru.
