For 9U and 10U players, a build out line will exist on the field. It is located halfway between the top of the penalty area and the halfway line. Its purpose is to define the area to which opponents must retreat when the goalkeeper has possession of the ball or at the taking of a goal kick.
Opponents must retreat behind the BOL for:
- Goal kicks
- When the goalkeeper has possession of the ball
And opponents must remain behind the BOL until the ball has been put into play.
When the goalkeeper has possession they may put the ball back into play by passing1, rolling, or throwing it.
- The goalkeeper is permitted, but not required, to wait until all opponents have retreated behind the BOL before putting the ball back into play.
- If the GK puts the ball back into play before all opponents have retreated behind the BOL, they suffer the consequences
- In enforcing the six-seconds rule, referees should not count time of possession until all opponents have retreated behind the BOL
- The GK may not punt or drop-kick the ball
- Sanction a violation with an IDFK to the opponents from the location of the offense. If the offense was inside the goal area, the IDFK is taken on the goal area line parallel to the goal line at the nearest point to where the infringement occurred2.
- Players cannot be penalized for an offside violation between the halfway line and the build out line.
- Players can be penalized for an offside violation between the build out line and the goal line.
- While doubtful, a team could use the BOL rule as a way of wasting time. This includes delay in retreating to the BOL and encroaching over the BOL before the ball is in play. Coaches are responsible for addressing this with their players.
- If a referee felt the coach was directing this, the referee should first talk to the coach. If the actions persisted, the referee is permitted to issue a yellow card misconduct (for delaying the restart).
- The referee's most important role unlikely will be to manage time wasting but in explaining the rule to new participants.
1 While simply putting the ball on the ground meets the technical definition of releasing the ball from their (GK) possession, the intelligent referee should enforce the opponents remaining behind the BOL until the ball has been kicked (passed). This will often look just like a goal kick with the GK putting the ball down in one of the two corners at the top of the goal area. Since it is being released from the GK's possession, even if it looks like a goal kick, it is not. Although, technically, the ball is in play when they have released it from their possession (hands), the spirit of this rule suggests that the ball is "in play" only after they have passed it. And since it is not a goal kick, it does not have to leave the penalty area and enter the field of play, but simply "passed."
