Masters Football was a six-a-side indoor football competition in the United Kingdom, where players over the age of 35 were chosen by the Masters Football Selection Committee to represent a senior club for which they played. Regional heats were held, and the winners of each progressed forward to a national competition. Events were contested over the course of a single evening (usually on Saturdays or Sundays), with games played in two halves of eight minutes each. The pitch was 60 m (200 ft) by 30 m (98 ft) (the size of an international ice hockey rink), and there was no offside rule.
