An Equaliser is a term used in football (soccer) to describe a goal scored by one particular team which has changed the scoreline of the match so the two teams playing are now currently drawing with one-another, rather than one of them winning.

For example, if Team A is winning 1-0 against Team B, but then Team B scores and makes the match 1-1, then that goal would be deemed an Equaliser.
