McCann says she had lots of lucrative offers from different promotions but opted for Matchroom because this is a “pivotal moment” in women’s boxing.

During her time in the UFC, McCann won seven of her 14 bouts with her highlights including two spinning elbow knockouts in 2022.

She exited the sport having won six of her bouts by knockout and claiming three performance-of-the-night bonuses, the most in UFC flyweight history.

Matchroom’s promotor Hearn says he “truly believes” McCann “will be a world champion” in boxing.

“What’s important to know, she really is a boxer first. You see a lot of fighters try switch from UFC to boxing because they’ve already built their brand but they’re not actually elite at the discipline,” said Hearn.

“It used to be a lot easier to win a world title in women’s boxing, now it’s a lot harder. We’re talking about Molly starting around the bantamweight level, there’s some really good fighters there.

“She’s not a novice, because she has amateur pedigree. The most important thing is to stay active.”

A date and opponent for McCann’s first fight under Matchroom is yet to be announced.
