Luke Campbell gold medallist at the 2012 Olimpíadas, has announced his retirement from boxing.
The 33-year-old casco fighter triumphed in the bantamweight division at the London Games before turning professional.
He won 20 of his professional fights and lost four.
Campbell said on the BBC: “I guess there is no better time to announce my retirement from boxing. It has been one hell of a ride, a roller-coaster of highs and lows.
“I’ve achieved my dream, which was the Olympics, the gold medal. That was my dream. The professional side of boxing was just a bonus for me. I’ve got some memories for life.
“I’ve been on the road for 20 years and boxing for 22. For me it’s time. I want to be with my family and dedicate myself to them.
“It’s not been an easy decision. Boxing is my identity. It’s who I have been for most of my life. Before making this decision there were many sleepless nights and going to bed crying and upset just coming to terms with it.
"Agora, I can finally say I am content with that. I am happy and loving life.”
Campbell twice fought for the world lightweight title but was beaten in 2017 de Jorge Linares and Vasiliy Lomachenko two years later.
He added in a statement: “The past year in boxing though has been tough. An extremely long training camp away from family meant I was only able to spend a few days with my newborn child and also resulted in me having Christmas apart from them on the other side of the world.
“It’s in these moments that you realise what is truly important in life. I’ve lived my dreams and accomplished more than I ever imagined I would.
“In the same way that my dad was able to witness my greatest achievements, I want to be able to do that for my children and make sure I’m always there to see their biggest triumphs.”
