Katie warned she faces battle in 'ruthless' pro boxing world
Olympic boxing champion Katie Taylor has turned professional not for the money but because she loves a challenge, her business manager Mark Devlin has said.
Her first professional bout will be in the SSE Arena at Wembley in London on November 26.
Irish boxing legend Michael Carruth, who wished her well, said professional boxing was "more ruthless" but believed Katie could give women's professional boxing "the kick in the a**e it needs".
However, he said if Katie earns €500,000 inside the ring over the next three years, she will have to divide much of her earnings with others.
Katie has signed a professional contract with Matchroom Boxing, and promoter Eddie Hearn said the Bray boxer will make her debut live on Sky Sports.
Two weeks later, Katie will fight in Manchester on the undercard to Anthony Joshua.
"When I first dreamed of Olympic gold, female boxing was practically unknown," said Katie. "Now, because of my journey and the incredible supporters who came along with me, it is as much a part of the fabric of the Olympics as male boxing.
"Now I want to do the same for the professional sport and I hope those who have supported me along the way will come with me. I'm excited for the road ahead."
Hearn said: "She is one of the most decorated amateur boxers of all time and a public icon in Ireland.
"I met Katie for the first time last week and was fascinated by her desire to not just win world titles but to break down the barriers of women's boxing. She is an incredible role model.
"Boxing is a sport open to all but it's also an entertainment business. Anyone who has watched Katie fight knows how exciting she is and anyone who hasn't is really going to enjoy her journey on Sky Sports."
Katie has won 2012 Olympic gold, five world titles and six European crowns.
However, since her father Pete left her corner, her form has slumped, losing three times in 2016 having previously remained undefeated since 2005.
Mark Devlin, of Devlin Sports Management, told the Herald he would not be able to speculate about her future earnings because the future is "a blank canvas".
"The world is her oyster. She will set the standard. She's not doing it for the money. She's doing it because she loves a challenge. Her going professional will help the sport. She's going to be global," he said.
Carruth, a former Olympic medallist who also turned professional, said: "Professional boxing is a business and she will be paid to entertain the punters.
"It's more ruthless. This could be the kick in the a**e it needs. She's has a great legacy in Irish amateur boxing."
In the 12 months to June, her firm earned €1.2m outside the ring.
