Early Saturday morning will see Taylor vs Serrano 3; the third instalment of a gripping rivalry between two of the top fighters in the women's game.
Taylor has won the first two meetings between the two. While the first win was comfortable, the second win was more controversial, and she'll be looking to confirm her dominance in what is sure to be a fight of the year contender.
Paddy Power have priced Katie Taylor as a narrow underdog at around 6/4, but new players can claim a huge 50/1 if they join today.
