The original use of the term "substitute" in football was to describe the replacement of players who failed to turn up for matches. Although substitutions were widely used in the Continent from the 1930s, it was not until the 1965-66 season that substitutions during matches were first permitted in English League Football. During the first two seasons after the law was introduced, each side was permitted only one substitution during a game. Moreover the substitute could only replace an injured player. It quickly became apparent that players were feigning injuries to allow for a substitution.  From the 1967-68 season, this rule was relaxed to allow substitutions for tactical reasons.  On 21 August 1965, Keith Peacock of Charlton Athletic (left) became the first substitute used in the Football League when he replaced injured goalkeeper Mike Rose eleven minutes into their away match against Bolton Wanderers.  Archie Gemmill of St. Mirren was the first substitute to come on in a Scottish first-class match, on 13 August 1966 in a League Cup tie against Clyde when he replaced Jim Clunie after 23 minutes. The first substitute to come on and score in a League match was Bobby Knox who netted for Barrow against Wrexham on the opening day of 1965-66.  Not content with making this little piece of English football history, four months later, on 27 December, Knox also became the first substitute to come on and save a penalty in a League match, after replacing injured keeper Ken Mulholland in Barrow’s 1-0 victory at Doncaster Rovers.  In latter years, the number of substitutes permitted in Football League matches has gradually increased, at present each team is permitted to name five or seven substitutes depending on the country and competition, of which a maximum of three may be used. In England, the Premier League increased the number to seven for the 2008-09 season although only three  canthree can be used. The prize for the best public announcement of a substitution goes to the public address system at Moss Rose during a Vauxhall Conference game which informed supporters of a Macclesfield substitution by announcing, ‘Macclesfield substitution: Power is off, so Coates on’.
