If the ball runs over the boundary after bouncing, the boundary umpire raises his arm vertically as he blows the whistle to point the ball is out of boundary. the sector umpires blows his whistle and signals a throwing action over his head to point to the boundary umpire to throw the football back to play.

If the football flies over the border on the complete , the boundary umpires raises both arms parallel to the bottom and indicates where the ball crosses the border for the sector umpire to put the opposition player on the mark to permit a place kick to be taken by the attacking player.

If the ball goes over the border but was touched on the wing , the boundary umpire raises one arm vertically and hits his raised arm 3 times to indicated it had been touched. Then if it appear to be kicked over on the complete but came off the leg above the knee, the boundary umpire will hit his knee 3 times to point this happening.
