One of Dana White's most coveted potential signees has her next fight -- and it'll be for a title.

Alexa Grasso will challenge Livia Renata Souza for the Invicta FC strawweight title in the main event of Invicta FC 14 on Sept. 12 in Kansas City, it was announced Thursday night at Invicta 13.

Grasso (7-0) has been mentioned many times by White, the UFC president, as one of the fighters he would most like to sign. The popular Mexican fighter is still under contract with Invicta and has said she would like to win Invicta gold before going to the UFC. Grasso, 21, is coming off a unanimous decision win over Mizuki Inoue at Invicta FC 11 in February.

Souza (8-0) just won the Invicta belt by submitting Katja Kankaanpaa in the fourth round at Invicta 12 in April. The Brazilian has a dominant ground game, which could present problems for Grasso, a potent striker. Souza, 24, has won all but one of her fights via submission.

No other fights have been announced yet for the card.
