'Excited to punch her' - Harper & Dubois make weight
But Harper has refused to be intimidated, shoving Dubois earlier in the week at a media day and exchanging elbow jostles during Thursday's photo call. "The game is over. It's all about tomorrow [Sunday].
It's not about the elbows, it's about the fists," Harper said. A three-weight champion, Harper has previously held titles at featherweight and light-middleweight but says she feels most comfortable at lightweight. "I naturally get down to this weight.
This morning I woke up on weight, I didn't need to take anything off," she said. Harper's record stands at 16 wins, two losses, and two draws, including fights against Natasha Jonas, Alycia Baumgardner, Cecilia Brækhus and Sandy Ryan. Dubois has 12 wins and one draw but is yet to face a marquee opponent.
A victory could set up unification bouts or high-profile fights against the likes of Baumgardner. "Look at my body and my physique. This year I've grown, I've got bigger, I've got stronger," Dubois said.
