Football 5-a-side teams are made up of four outfield players and one goalkeeper, Paralympic.org wrote.
To ensure fair competition, all outfield players must wear eyeshades. Teams can also have off-field guides to assist them.
The ball makes a noise due to a sound system located inside that helps players orientate themselves. As a result spectators must remain silent whilst watching the game until a goal is scored.
Blind football is played on a rectangular field that measures 40m long and 20m wide. The whole length of the pitch must be covered by kickboards to prevent the ball from going out of play.
The duration of the match is 50 minutes, divided into two 25-minute halves. Each team can request a one-minute time-out in each half. During the last two minutes of both halves, and in case of an extra time, the timekeeper must stop the clock for a free kick, kick-in, goal kick and corner kick.
