Basic line and goal rules of association football
Association football is the other name of soccer. It is played using a spherical ball. The game is played between two teams, each consisting of eleven players. There are also some substitute and reserve players in each team. The eleven players which start the game from each team are collectively called the ‘starting XI’. If the stamina of one or more players is depleted, then he/she is substituted and a fresh player is brought into the action. A team can substitute up to three players, i.e. no more than three substitutes are apportioned for each team. Before the start of a match, players are swapped and fresh players are brought from the substitute and reserve squad into the starting XI. Also, after the halftime break, some players are substituted due to low energy levels and/or morale. Players are also substituted in case of physical injuries.
The advent of professional association football was in the nineteenth century in England. Thus, the laws of the game were formulated and implemented in the game by the Englishmen. The IFAB (International Football Association Board) was the governing body which determined the laws of the game. As of now, such rules are being implemented in the game, with some slight modifications. Minor modifications include the conversion of the units used for measurements of the football pitch. Since Imperial units were used for the measurements of the pitch, they are now converted to SI or metric units. However, they are not very accurate due to the use of decimal points. Again, the measurements vary from league to league. IFAB took an initiative to standardize the measurements in 2008, but the decision regarding the approval of such initiative is still pending.
Now, some basic line rules regarding association football are-
1) If the ball is on or over the touchlines and/or the goal lines, then the play is to be continued.
2) Outside is considered only when the ball goes completely out of the touchline and/or goal line.
3) If the player of a team sends the ball out of the touchline, then a throw-in will be awarded to the opposite team.
4) If the player of a team sends the ball out of the goal line, then a corner will be awarded to the opposite team.
The above rules also apply while scoring a goal. The ball must cross the goal line completely in order for a goal to be scored. Also, if the goalkeeper of one team handles the ball from within the goal line, then it will be considered as an own goal and the opposite team will be awarded with a goal. If the defender of one team commits a foul or violates a rule within his/her respective D-box, then the opposite team will get a penalty kick. If the same thing appears outside the D-box, then a free-kick will be awarded to the opposite team.
Thus, from the above discussion, on m88a we can get a brief notion about the basic line and goal rules of association football.
