Dubois has sniped at Harper time and again over the past three months<\/a>, and their verbal back-and-forth will give way to a title-unification clash on Sunday<\/a>. <\/p>\n At London\u2019s Olympia, Dubois will defend her WBC lightweight belt against her British rival, who defends the WBO title in the main-event showdown. The women-centric card<\/a> includes three other world-title fights<\/a>, too, featuring British talents Chantelle Cameron, Ellie Scotney and Emma Dolan.<\/p>\n Harper, a three-weight champion, has been much-less loquacious than the unbeaten Dubois in the build-up, and the same was the case at Friday\u2019s press conference, where Dubois repeatedly taunted the 29-year-old.<\/p>\n Dubois, 25, initially pounced when Harper said: \u201cCaroline just said herself, \u2018talk is cheap\u2019, and that\u2019s all she\u2019s done these last 12 weeks. I\u2019ve been fully focused on this job that I\u2019ve got to do on Sunday night. You\u2019ll see I\u2019ve been quiet on my socials, whereas Caroline\u2019s been arguing online, getting sucked into everything.\u201d<\/p>\n Dubois responded: \u201cDon\u2019t project, Terri. If that\u2019s what would distract you, that\u2019s fine. I\u2019m an elite athlete. I\u2019ve been doing this since I was 9 years old. I\u2019m not a weak individual, I don\u2019t get sucked in by noise, I run towards the fire. You can say what you want about your own projection, maybe this is what would scare you.\u201d<\/p>\n The subject of fear arose again later in the press conference, when Harper was asked what she would bring to Sunday\u2019s main event and said an \u201cengine\u201d. <\/p>\n \u201cThat\u2019s it? That\u2019s a bit sad,\u201d Dubois jibed. \u201cI\u2019d hate to be going into a fight thinking: \u2018All I\u2019ve got is an engine.\u2019 That\u2019s a bit scary.\u201d In response to her opponent\u2019s taunts, Harper said Dubois would be bringing \u201ca mouth\u201d into Sunday\u2019s grudge match.<\/p>\n Enjoy 185+ fights a year on DAZN, the Global Home of Boxing<\/p>\n Never miss a fight from top promoters.
