Tradition has won for now with the AFL sticking with a 2.30pm AEST bounce for this year's Grand Final.

Chief executive Gillon McLachlan confirmed the decision on Friday morning.

The debate about moving the Grand Final to a twilight timeslot intensified as the new $2.508 billion media rights deal began.

McLachlan said he expected the decision to be popular with fans.

Speaking on ABC Radio, McLachlan said there hadn't been "anything really scientific about it."

The League confirmed on Friday morning the Commission had accepted McLachlan's recommendation to keep the game in its traditional Saturday afternoon slot for this season.

The Grand Final will be staged at 2.30pm AEST on Saturday, September 30.
