21-8-1965: Charlton’s Keith Peacock was the first substitute to be used in the English Football League when he replaced the injured goalkeeper Mike Rose 11 minutes into their away match at Bolton. Only one substitute was allowed and the substitution was only allowed due to injury. This rule was changed in 1967-68 when substitutions for tactical reason where allowed.
On the same day the first substitute to score in a League match was Bobby Knox for Barrow versus Wrexham in a Division Four game.
