Holly Holm, who has won countless titles inside the boxing ring, will leave the sport for MMA following a May fight.

Holm made the announcement earlier this week, confirming that May 11 will be her final boxing match. She will defend her two titles against Mary McGee before embarking full-time on a career in MMA.

“Since I first started fighting, it became my passion,” Holly explained her decision. “I decided a long time ago, after quitting school to fight, that I would box as long as my heart was in it. One of my biggest and controversial fights was against Christy Martin. Then, it was Mary Jo Sanders. There’s always a champion. This is my own journey. Every one of my fights have helped me to believe in myself.

Holm sports a 32-2-3 record inside the squared circle, while she is a perfect 3-0 in the cage. She owns titles in three divisions and is 21-1-1 in world title matches.

“When we were deciding which way to go with my future, my trainer, Mike Winkeljohn, said it best, ‘You want to climb a new mountain.’ This thing has created a new spark in me and I’m following my heart. I wish much success to Cecilia (Braekhus) but not fighting her does not, by any means, define my boxing career. I know there’s a lot of talk about that but what does that say about all the women I’ve already fought? I’ve never been a paper champion. I’ve grown so much every step of the way. I’m in this fight, on May 11,100 percent; I’m not distracted. This is obviously an emotional, spiritual and physical journey and I’m so grateful for the people who have supported me. I just want to fight where my passion is (MMA). I train in an MMA gym and always have.”

Holm obviously has the credentials to become a star in MMA, but she will need time. Training with Jackson’s MMA should give her a strong base to build upon.
