The AFL is considering trialling major rule changes in up to three games for premiership points before this season is over.

AFL chief executive Gillon McLachlan has revealed conversations at League headquarters in recent days have identified possible games which will have no bearing on the finals in which trials could take place.

"Certainly thinking about it," McLachlan told SEN radio on Wednesday morning.  

"I can tell you that there's three fixtures on consecutive weekends that I don't think will have any bearing on the eight, as we stand today ... we've got another couple of weeks to play.

"I know enough to know there's fixtures available to do it and we're certainly discussing whether that's appropriate, and the emerging view is that I think it is."

McLachlan said trials in the season-proper would have significant benefits. 

"You get to see it in real time, in a game, with four points, with a win and loss on the end of it."

And the League chief insists if the competing Clubs agreed he couldn't see "any way that there can be a risk to the integrity of the competition".

It comes ahead of the League's newly formed Competition Committee meeting on Wednesday afternoon.
