It’s in the rules how to restart play when a ball bursts. But it’s more theory than practice.
Tonight, I saw for the first time that a ball actually bursts during play. It happened in the match between Bayern Munich and Cologne in German Bundesliga this Friday evening.
Laws of the Game about bursting balls:
“If the ball bursts or becomes defective during the course of a match:
• the match is stopped
• the match is restarted by dropping the replacement ball at the place where
the original ball became defective, unless play was stopped inside the goal
area, in which case the referee drops the replacement ball on the goal area
line parallel to the goal line at the point nearest to where the original ball
was located when play was stopped.”
UPDATE: One of the readers mentioned the 1966 World Cup final between USSR and Hungary, where also a ball bursts.
