Dana White announces new UFC signing and immediately makes UFC 300 fight, no one saw this coming

Dana White has announced a new UFC signing and immediately made a massive fight for UFC 300.

The blockbuster card goes down in Las Vegas, Nevada, on April 13.

A UFC women's strawweight title fight between Chinese stars Zhang Weili vs. Yan Xiaonan and a BMF showdown between Justin Gaethje and Max Holloway are scheduled for the monstrous event.

Not to mention a UFC lightweight title eliminator between former champion Charles Oliveira and top contender Arman Tsarukyan.

And the card will now see a UFC debutant make her long-awaited Octagon bow as White confirmed a huge new fight for UFC 300. Check it out below:

On Tuesday, the UFC CEO announced the signing of Kayla Harrison, who has signed an exclusive deal to join the UFC, where she will compete as a bantamweight.

Harrison, 33, is finally a UFC fighter, having fought under the Professional Fighters League (PFL) banner.

And White has wasted no time in matching her up as the two-time Olympic gold medalist judoka will take on former UFC champion Holly Holm.

Harrison vs. Holm could determine the next challenger for the UFC women's bantamweight title, which is in the hands of Raquel Pennington following her victory over Mayra Bueno Silva at UFC 297.

Harrison, meanwhile, is a two-time PFL women’s lightweight champion and boasts a professional record of 16-1.

She hasn't fought since her victory over Aspen Ladd last November.

The American has spent her entire career competing at either featherweight or lightweight but will compete in the UFC's women's bantamweight division.

Last November, she said: "I mean, 135 will challenge me in ways, like I’m going to have to lose a piece of me to be able to fight at 135 pounds.

"I think just structurally, I carry a lot of muscle. I’m already kind of lean, so I’m going to have to lose muscle. I’m going to have to change my entire lifestyle. I mean, I have already done that to fight at 145.

"It’s crazy what happens when you take care of your body and eat properly and sleep and recover. I was a knucklehead when I was younger. But I have faith whatever is meant to be, will be."
