Katie Taylor and Amanda Serrano will butt heads again after their historic meeting in Madison Square Gardens for what was one of the greatest female fights of all time. On any other night, Taylor-Serrano 2 would be at the top of its own fight card, such is the prestige and rivalry between these two athletes.

Katie Taylor and Amanda Serrano's long-awaited rematch Friday as the Tyson vs. Paul co-feature will likely be the most-watched women's boxing bout in history.
