AFL players who win free kicks for high tackles by lifting their arms or lowering their legs might not next season, under changes being considered.

The issue is one of numerous discussion points between the AFL and its clubs and players as the league weighs up whether to alter any laws of the game or interpretations for 2013.

Other topics include the interchange rules, with AFL football operations manager Adrian Anderson confirming on Wednesday that a move to two interchange players and two substitutes was a possibility, although it is not supported by clubs or players.

“Most clubs aren’t in favour of going down the track of two-two at this point in time,” Anderson told reporters.

Another proposal is to cap interchanges at 80 per team per match, although Anderson said the AFL might also leave interchange rules as they are.

The league could also crack down on players who crash into opponents’ lower legs with their head or upper body, similar to this year’s tightened interpretation on players sliding into opponents knees or feet-first.

Other rule changes under consideration include not allowing ruckmen to make contact with each other until the ball leaves the umpire’s hand at a ball-up, a variation of which was trialled during the pre-season.

But Anderson stressed that the AFL was only at the discussion stage and any law or interpretation changes would not be confirmed until October.

On the issue of players deliberately trying to earn free kicks for high tackles, highlighted by coaches at times this season, particularly in relation to West Coast players, Anderson said the AFL might need to respond to emerging tactics.

Some players burrow into contests head-first, others shrug their arms and lower their legs so tackles slip higher, while others forcefully lift opponents’ arms with “upper cuts”.

“What they’re doing this year is if a guy shrugs and the tackle starts low and finishes high, they’re paying a free kick,” Anderson said.

“I think that’s pretty clear.

“The question is `Should they?'”
