The decision comes as a result of a meeting held between the IWRF, chair manufacturers, athletes and the IWRF Technical Commission.

After the World Championship, which is due to take place from August 5 to 10, a working group will be established to work through the definition of a ball holder for the sport of wheelchair rugby.

The rule to enforced at the event states that players may use additional devices to support the ball and that this support must be level with or higher than the seat frame.

It adds that no part of the ball can rest within the seat frame and that straps may be used to secure the ball as long as 75 per cent of the ball is available to be played and only makes contact within the bottom 25 per cent of the ball. 

Officials have been instructed to be vigilant on the 75 per cent of the ball available to be played.

The Technical Commission also advises teams that if 75 per cent of the ball is not available to be played, the chair is illegal and a team may protest it.

If the protest is upheld, the chair will be removed from the game and cannot return until checked by the referee at a quarter-break or half-time.

World Championship matches will be played at the Quaycentre at the Sydney Olympic Park.

Hosts Australia, the Rio 2016 Paralympic gold medallists, will be looking to defend the world title they won in Odense in Denmark in 2014.

They will play in Pool A with Japan, Sweden, New Zealand, Denmark and Ireland.

Pool B contains the United States, Canada, Great Britain, France, Colombia and Poland.
