This Saturday night in Ireland, a showdown between two undisputed world champions.
Katie Taylor, the undisputed champion at 135-pounds, is heading up to 140 to face the undisputed champion of the weight class, Chantelle Cameron.
Both are undefeated.
Taylor was originally scheduled to face Amanda Serrano in a rematch - but the fight was called off when Serrano withdrew with an injury.
In a very unexpected move, Taylor called for a fight with Cameron.
Eddie Hearn of Matchroom promotes both boxers and it became an easy fight to make, as both champions were eager to get the deal done.
Taylor is the hometown hero - and despite being the challenger much of the attention has been centered on her, with many observers already discussing Taylor's options beyond this contest.
"I have a fire in my belly," Cameron said to BBC Sport. "The amount I have been overlooked, already people are looking past me.
"I'm the champion, I've got the belts, but I'm not being treated like that."
Cameron is growing in confidence as the fight creeps closer to the date.
"As much as there have been ups and downs it's all going to make a better story in the end," Cameron said.
"When I started my career, I wasn't the most confident person. My confidence is flying but I think that's down to the people around me, they boost me up. Sometimes I think they're just saying it to make me feel good, but I'm also backing it as well.
"It's two undefeated champions, two undisputed champions - doesn't get bigger than that. I'm making my own legacy, showing people that I'm not afraid to put myself out of my comfort zone. I'm confident enough to go to different people's countries and fight them - especially against Katie Taylor, she is a boxing legend and not just in Ireland."
