Molly McCann said she "didn't even get out of second gear" as the former UFC star launched her professional boxing career with an impressive technical knockout victory.
The 35-year-old Liverpool native stopped Ireland's Kate Radomska in the final round of their six-round super bantamweight contest on the undercard of Lewis Crocker and Paddy Donovan's world title fight at Belfast's Windsor Park.
McCann landed several heavy shots during an impressive debut and dropped Radomska in the fifth round with a hard right hand.
However, she was also forced to compose herself after Radomska appeared to kick out at her in the second round while defending an attack from McCann in the corner.
"It was very different so I was happy with it," McCann told BBC Radio 5 Live.
"I think I took a kick and a headbutt and I give out some knocks as well so I'm happy. I didn't even get out of second gear there so that was nice."
