Players experimented with kicking the ball in after a behind from 25 metres out from the goal line in another trial of new rule proposals during a scratch match between Brisbane Lions' players that was held in front of AFL officials at the Gabba on Tuesday.

The rule is one of the options the AFL is considering to widen the ground and make it easier for teams to transfer the ball from one end of the ground.

The trial was the second secret session overseen by AFL officials to trial potential rule changes being considered to ease congestion and create opportunities to score.

The first trial was held last Saturday when the AFL filmed a Hawthorn training session at Etihad Stadium where players were asked to trial starting positions at centre bounces.
