Anthony Joshua has made his first public appearance since he was beaten by Andy Ruiz Jr.
The Brit lost his three heavyweight world titles to the huge underdog in New York earlier this month.
He returned to London shortly afterwards and headed straight for the gym after triggering the rematch clause in his contract.
And on Wednesday Joshua joinedPrince Harryat the launch of a campaign designed to bring together charities supporting disadvantaged young people through sport.
Made by Sport aims to take advantage of the proven role sport can play in developing skills that make a difference at school, work and life.
The new campaign will also raise vital funds to support sports provision and grassroots clubs and organisations in disadvantaged communities across the UK.
Joshua and Prince Harry were joined by another Olympic champion in Nicola Adams as they led a boxing training session with young people.
Joshua was a short odds-on favourite to beat Ruiz and continue his dominance of the heavyweight division.
But after dropping his challenger in the third round, Joshua himself was sent to the canvas twice in the same session.
He recovered but was dropped twice in the seventh stanza before the fight was stopped.
Joshua’s domestic rivalTyson Fury, meanwhile, has claimed Joshua is “finished”.
He told BBC Sport: “When a man doesn’t want to be there once, he will always do it and it’s hard to come back from.
“He did it that night and I don’t think he will come back from it. Finished. Ask any top trainer who has been around the sport a lifetime. When he got to the ring I saw he didn’t want to be there.
“Everybody thought that man could beat me. In what world could he ever beat me? What were people seeing?
“I don’t know what people were looking at as I don’t know in what world he could have beaten me.”
