Serrano's bout with Taylor was unarguably the biggest fight of the night aside from the Mike Tyson-Jake Paul main event. However, it took a concerning twist after Serrano's eye cut.

The rematch between Katie Taylor and Amanda Serrano was as bloody and bruising as the original. The disputed decision — and the reaction to it — was the same, too. Taylor retained her unanimous super lightweight championship in a razor-thin unanimous decision over Serrano on Friday night in a slugfest remarkably similar to their epic bout in New York two years ago.
