Rio Ferdinand is launching a new career as a professional boxer, two years after he retired from football.
The 38-year-old's move into the ring is being backed by betting company Betfair, which announced the news on Tuesday, reports BBC.
Former Manchester United and England defender Ferdinand works as a TV pundit and he has his own clothing line.
"I'm doing this because it's a challenge," he said. "I've won titles and now I'm aiming for a belt."
He has posted several social media videos in recent months showing him boxing and working with personal trainer Mel Deane.
Ferdinand, who won the Premier League six times and the Champions League once during his time in Manchester, may follow in the footsteps of former Birmingham City midfielder Curtis Woodhouse and former Crystal Palace forward Leon McKenzie, who became professional boxers after quitting football. Woodhouse became British super-lightweight champion.
Former England cricket captain Andrew Flintoff also launched a boxing career after retiring, winning his only pro bout in December 2012 against American Richard Dawson at Manchester Arena on points.
It was Betfair who approached Ferdinand about making the switch, and the betting company will help him qualify for his British Boxing Board of Control licence before he begins training and competing.
The company previously backed Victoria Pendleton in her transition from Olympic cyclist to Cheltenham jockey.
"When Betfair approached me about the challenge, the chance to prove myself in a new sport was a real draw," added Ferdinand.
He will be coached by Team GB coach and former WBC super-middleweight champion Richie Woodhall.
"In all honesty, I think Rio can definitely box as a professional given time. He has natural power in his right hand, is extremely fit and is very enthusiastic to learn which is encouraging," said Woodhall.
