Editing Polo (section)

=== Outdoor polo ===
Outdoor or field polo lasts about one and a half to two hours and consists of four to eight seven-minute chukkas, between or during which players change mounts. At the end of each seven-minute chukka, play continues for an additional 30 seconds or until a stoppage in play, whichever comes first. There is a four-minute interval between chukkas and a ten-minute halftime. Play is continuous and is only stopped for rule infractions (fouls), broken tack (equipment) or injury to horse or player. The object is to score goals by hitting the ball between the goal posts, no matter how high in the air. If the ball goes wide of the goal, the defending team is allowed a free "knock-in" from the place where the ball crossed the goal line, thus getting ball back into play.<ref>{{cite web|title=RULES OF THE GAME – United States Polo Association|url=https://www.uspolo.org/sport/rules|website=United States Polo Association|access-date=8 November 2017|archive-date=12 July 2017|archive-url=https://web.archive.org/web/20170712123404/https://www.uspolo.org/sport/rules|url-status=live}}</ref>
