A line-out or lineout is a means by which, in rugby union, play is restarted after the ball has gone into touch. When the ball goes out of the field of play, the opposing team is normally awarded a line-out; the exception is after the ball is kicked into touch from a penalty kick, when the team that was awarded the penalty throws into the line-out. In 2021 World Rugby began trialling what was dubbed the "50:22" (or "50–22") rule, wherein the kicking team has the throw-in if the ball travels from the kicker's half and bounces beyond the opposing 22-meter line. This was inspired by rugby league's 40/20 kick. A line-out is formed by players from each team lining up inside the touchline, at 90° to it. A player from the side that did not put the ball into touch then throws the ball back into play. A line-out is one of the two methods of restarting play after the ball has gone into touch, the other is the "quick throw-in" (sometimes referred to as a quick line-out). Due to the specific rules placed on quick throw-ins they are uncommon in a rugby match, with the majority of restarts from touch taking the form of a line-out. Line-outs Position of line-out Where the line-out is taken depends on the manner in which the ball was played into touch. If it is kicked directly into touch, without first landing in the field-of-play or touching the referee or an opponent who is not in touch, the line-out is formed in line with the spot from where it was kicked, with two exceptions: if the kick was a penalty kick or if the kicker had at least one foot on or behind his own 22-metre line, the line-out is formed at the spot where the ball crossed the touch-line. In all other cases, the line-out is formed at the spot where the ball crossed the touch-line, except that if this spot is within 5 metres of the goal-line, the line-out is formed on the 5-metre line. A line-out is also awarded if a player in possession of the ball crosses or touches the touchline whilst still in possession of the ball. A player in the line-out will attempt either to catch the ball or to knock it back to a "receiver", a player from their own side (often the scrum-half but sometimes
