Corner flags are located at the four corners of the pitch, where the touchline meets the tryline.

If a player knocks into the flag in the process of putting the ball down, the try is disallowed even if the player's feet and body are not in touch.

So the new laws have removed the flag from the equation.

"At the moment tries are being disallowed when the corner flag gets taken out, so we're saying just get rid of it," said O'Brien.
