PLAYERS have expressed concern at AFL proposals to limit the on-field activity of officials such as trainers and runners at the annual AFLPA delegates' conference.

They told laws committee representatives on Wednesday if such a move was made it could impact negatively on player wellbeing, with fears the players may not be able to hydrate effectively or receive apporpriate treatment for injuries.

Late in the season AFL football operations manager Mark Evans had raised the issue of limiting the time officials spend on the ground and asked for club feedback.

There was concern that officials were crowding zones or were getting in the way of play and giving away free kicks.

"I am keen to explore whether we can reduce this impact by limiting the time frame, or the number of times, in which some of the officials are on the arena," Evans told at the time.

However player representatives believe the AFL should monitor the situation throughout 2014 rather than making an immediate change to the number of officials on the ground or the times in which they can enter the arena.

They think the issue can be resolved through stricter enforcement of the existing rules relating to the on-field activity of club officials.

At the laws summit on the Gold Coast in November coaches expressed serious misgivings about any limitation being placed on the number of runners or the times they could enter the arena.

The coaches were concerned about the impact it would have on their ability to coach and were of the view that the change was too significant to introduce so close to the new season.

One suggestion being made is for officials such as trainers to wear neutral rather than club colours to make them easier to distinguish from players.

The AFL Commission is expected to hear proposals in relation to rule changes before the end of the season.

It has already introduced an interchange cap limiting the number of rotations to 120 per game, plus changes at breaks.

Football and list managers were informed on Tuesday in a meeting with the AFL about the way such rotations would be recorded.

The AFL hopes to introduce a system that communicates the number of rotations being made to the coach's box, the broadcasters and the scoreboard simultaneously.

Football managers were told interchanges for the blood rule would not be counted in the tally but the full detail would be communicated to clubs in due course.

The AFLPA delegates two-day meeting concluded on Wednesday with player representatives hearing about the anti-doping code, equalisation and discussing representative football.
