James DeGale has retired from boxing following his unanimous points defeat by Chris Eubank Jr.

The 33-year-old, a two-times world super-middleweight champion and the 2008 Olympic middleweight champion, was the first British boxer to win an Olympic gold medal and a professional world title.

DeGale said: “Today marks 10 years since my professional debut fight on February 28, 2009, and today is the day I am announcing my retirement from boxing. It’s been an unbelievable journey and I’ve had an amazing decade – if I’m honest, the best years of my life.”

The Londoner rose to prominence in 2015 when winning his first world title belt, against Andre Dirrell in the US, before defending it three times across the Atlantic.

He said: “It’s hard to admit I’m not the fighter I once was but I’m human and along the way my injuries have taken a toll – both on my mind and body, and these things have contributed to my performance in the ring.

“I lost the fight on Saturday at the O2 but I’m touched to have a good send-off from the fans in my home city. I’m proud to say that I’ve made history as the first ever British Olympian boxer to turn professional and to win a world title and I am also proud to have been a road warrior – to travel wherever I needed to be to fight and win. There’s nothing left to prove.”
