The team that did not kick off will do so at the beginning of the second half.The kick-off is taken from the center spot and the ball must move into the opposition's half. After a goal, the kickoff is given to the team that has been scored against.elow is the procedure: 1  the ball must be placed stationary on the center spot. 2  all players must be on their respective halves before the ball is kicked. 3  players from both sides who are not kicking off should be outside the center circle (10 yards away from the ball) until the ball is played.
