Former QPR defender Rio Ferdinand has announced plans to become a professional boxer.
The 38-year-old, who works as a football pundit for BT sports, is taking part in the "Defender to Contender" project in conjunction with online betting company Betfair.
Speaking to the Evening Standard, Ferdinand said: "A lot of people sit and watch huge fights, plus other sporting events and say 'I can do that' or 'they've messed it up'.
"There are a lot of armchair fans wanting to pass judgement. Well, I'm going to walk the walk and actually do it.
"I'm doing this for many reasons. I'm doing this to test myself as a man, as a human being.
"This is a test of my mind and body, that's the way I'm looking at it. I'm not looking at it to become the world champion, I'm not stupid."
Ferdinand won six Premier League titles during his career, featuring for clubs such as West Ham United, leeds United, Manchester United and the Hoops, as well as winning 81 caps for England.
