Suffering just a singular career defeat since her transition to mixed martial arts, Kayla Harrison suffered a decision loss to three-time foe, Larissa Pacheco in the pair’s lightweight tournament finale, having previously racked up to wins over the Brazilian.

During the course of her professional career, Kayla Harrison, a two-time Olympic gold medalist in Judo, fought just once under the banner of the Shannon Knapp-led Invicta FC, has turned in notable victories against the likes of the above-mentioned, Pacheco, as well as Mariana Morais, Genah Fabian, Kaitlin Young, and the previously stated, Ladd.

As for Holm, the former undisputed bantamweight championship holder and inaugural featherweight title chaser, shocked the world in its entirety at UFC 193 back in 2015, handing inaugural bantamweight champion, Ronda Rousey a thunderous second round high-kick KO loss in the pair’s heated title grudge fight.

Attempting to make a bantamweight career walk for the first time since her move to the sport back in 2018, Kayla Harrison has competed exclusively at the lightweight limit in the Peter Murray-led PFL.

And with that added caveat, fans and punters alike will be keeping a rather close eye on whether or not the Ohio native can successfully make the bantamweight limit in her April debut – ahead of potential blockbuster fights for gold, and continued speculation regarding a return for Amanda Nunes from her retirement in June of last year.
