Leading up to UFC 300, Dana White has confirmed the UFC has signed Kayla Harrison to an exclusive contract.
In the announcement, White also revealed that the newly-signed Harrison will face off against Holly Holm at UFC 300 in Las Vegas in April - the event is set to become the biggest MMA event of all time.
Harrison, 33, is a two-time Olympic gold medalist in judo and will join the promotion from the rival Professional Fighters League (PFL), where she became a two-time champion.
"We're extremely grateful for Kayla's amazing career in the PFL," her manager Ali Abdelaziz told ESPN.
"She became the fighter she is now with their support. We are nothing but grateful to them and are excited to start a new chapter in the UFC."
Her arrival at the UFC will see her take on former UFC and boxing champion Holly Holm.
Known for dethroning Ronda Rousey many years ago, Holm is looking to make one final run to win the UFC championship and is 4-1 in her past five bouts.
It is understood that a win by either of the two competitors would see them earn them enter title contention. However, this will be after Raquel Pennington will take on former champion Julianna Pena in her first title defence.
