It started out as a caring father's message of support for his son who had been abused online for being too "big" to play rugby.
Now, Alfie Pugsley is the talk of the sport, the subject of a wave of well-wishes and inspirational replies from many of rugby's most famous players and teams who have offered some unlikely opportunities to the 11-year-old from south Wales.
His father, Mark, tweeted on Sunday to say he had removed a post on Facebook because "an idiot commented saying my boy is too 'big' to play under 12s and isn't healthy."
"If only people knew how hard he works to get fitter and how low his confidence has been," Mark Pugsley wrote in his post, alongside a picture of Alfie wearing his rugby uniform while playing for Oakdale RFC in Caerphilly, Wales. "Don't worry Alfie I'll always be your biggest fan."
It sparked a flurry of responses from players like World Cup winners Tendai "The Beast" Mtawarira of South Africa and Jerome Kaino of New Zealand, the official accounts of the All Blacks, England and Ireland teams, and players from different sports across many countries.
