Rubber match

A rubber match is the deciding match of a multi-bout series between two boxers, in which the two boxers have each won a bout against each other. The term usually refers to the third bout in a series, making it a trilogy.

There also have been examples in the modern era in which a draw in an earlier bout has made the fourth bout the "rubber match." This bout is usually seen as the match that determines which boxer has superiority over the other.
