Briton Natasha Jonas and Mikaela Mayer comfortably made weight for Saturday's IBF welterweight contest in Liverpool.

Jonas, 39, defends her title in front of a home crowd against Mayer at the MS Bank Arena.

She hit the scales at 10st 6lb to a roar of support, with Mayer just five ounces heavier.

American Mayer promised an "action-packed fight", adding: "Anyone who has seen me box [knows] I don't like to stand back and wait and take my time."

Mayer is a former unified super-featherweight champion and will be fighting in the 10st 7lb welterweight division for the first time.

But the 33-year-old, who boasts a height advantage over Jonas and looked at ease at the weigh-in, says she is is not concerned by the jump in weight.

Mayer said: "I feel great. [Making weight] is still tough for me. It shows how naturally big I am. I carry a lot in my height and frame. I still had to diet and cut for this but it wasn't as long as strenuous."

There was a huge reception from the home crowd as Toxteth-born Jonas made her way to the stage and smiled to the crowd while flexing her muscles.

"The home advantage is always big, that's why fighters opt to fight in their home cities, to get that support and motivation behind them," she said.

Jonas stopped Kandi Wyatt in July to win the vacant IBF welterweight title and become a two-weight world champion.

She has picked up four world titles in two different weight classes in 22 months, but the history-maker says she is only searching "legacy fights" at the backend of her career.

"Without winning on Saturday, they don't happen so I have to concentrate," she told BBC sport earlier.

Jonas became Britain's first female Olympic boxer when she competed at London 2012. In October she also became the first black woman to obtain a British Boxing Board of Control manager's licence.

"I want to be able to say when I hung up the gloves that I was one of the best of this era," she added.

"To do that you've got to be beating names on the top 10 pound-for-pound list and Mikaela Mayer is one of the names on it."
