He has been accepted for surgery in the United States, which will give him a better chance of walking on his own — but it comes with a $150,000 price tag.
McClelland played rugby with Harry's dad, Hayden, years ago and offered to give them the ring to auction. ''I think it's [the ring] just the final reminder of what was not meant to be,'' he said.
''I just really felt that someone else could benefit from it.''
Harry's story had ''tugged" at his heartstrings.
McClelland took the ring to the Finchs' house on Monday night and met Harry.
''He's adorable. I'm a bit of a tough guy but stuff like that . . . I'd hate to think what they are going through.''
Although the ring was worth about $1600, he was unsure how much could be raised from it.
''If it's marketed well and shared well with all of my followers, then it's one of those things, who knows?
"I think anything would help.''
Harry's mother, Bex, said they were overwhelmed by the gesture.
''We couldn't believe it.
''It's just the thought really that counts more than anything, and the fact that he would offer that to us.
''He was trying to find the perfect charity to give to and for him to pick Harry is pretty cool.''
McClelland was enjoying life after the show, which had ''opened the doors'' to other ventures.
''I am in a position where I am about to help a lot more people. I think that's really what I'd like to do with it.''
He made ''great friends'' on the show, with whom he still keeps in touch. ''It's funny because the only person I don't talk to is my wife,'' he joked. ''Ex-wife.''
