Post-match
Some time after the match, Kinnaird informed the council of the Football Association (FA), of which he was a member, that in his opinion he had not carried the ball over the line for Oxford's goal. Despite the fact that the referee had awarded the goal and multiple newspaper reports stated that the ball had clearly gone over the line, Kinnaird's fellow council members took his word for it, and struck the goal from the records, changing the official score to 2–0 (although if Oxford had not scored, there would have been no reason for the game to go to extra time, so by rights they should have annulled Wanderers' second goal as well). For the next century, all sources reported the score of the match as 2–0. In the 1980s, after fresh research into contemporary reports of the game by football historians, the FA reinstated the Oxford goal, and now regard the official final score of the 1877 final as 2–1.
