It took place on 5 May 1973 at Wembley Stadium and was contested between Leeds United, the previous season's winners and one of the dominant teams in English football at the time, and Sunderland, then playing in the Second Division.
In one of the biggest shocks in the history of the competition, Sunderland won 1–0 to become the first Second Division side to lift the Cup since West Bromwich Albion in 1931.
Sunderland's team were the only FA Cup winners of the 20th century not to field any full internationals,[citation needed] although some of their players were capped later.
Assisted by Dave Watson between two defenders, the deflected high ball was controlled by Ian Porterfield who shot home from 12 yards.
The save is considered one of the greatest of all time and has been compared with that made by England's Gordon Banks in the 1970 FIFA World Cup match against Brazil.
