'She kept headbutting me': Amanda Serrano on defeat to Katie Taylor – video

Katie Taylor remains the undisputed super lightweight champion of the world after she beat Amanda Serrano 95-94 on all three scorecards in a controversial bout. The evenly matched fighters went toe to toe for 10 rounds but Taylor was warned for excessive use of her head and in the eighth round she was deducted a point.

After the fight in Dallas, Serrano said: 'She [Taylor] kept headbutting me but we knew that from the very beginning.' Taylor defended her tactics and called the fight, which was the main undercard contest to the Jake Paul v Mike Tyson bout, 'an absolute slugfest.'
