Build-Out Line:

• The build-out line promotes playing the ball out of the back in a less pressured setting. 
• The build-out line shall be placed across the field equidistant between the top of the penalty area and the halfway line.
• The opposing team must move back behind the build-out line for a goal kick or when the goalkeeper has possession. At any time, the goalkeeper may pass, throw or roll the ball to a teammate who is behind the build-out line.
• The goalkeeper or the player taking the goal kick does not have to wait for the opposing players to move behind the build-out line. The play from the goalkeeper or from the goal kick must be played to a teammate behind the build-out line. After the ball is put into play, the opposing team can cross the build-out line and play may resume as normal. The first touch is from the goal kick or the pass from the goalkeeper.
• The build-out line shall be used as the line to determine offside. Players cannot be penalized for an offside offense between the halfway line and the build-out line.
