Twickenham, United Kingdom: All Blacks centre Sonny Bill Williams gave his World Cup winner's medal to a boy who he said was tackled by a Twickenham security guard after Saturday's final.
Williams said the boy was "smoked" -- thrown to the ground -- by a security official after running on to the field following the All Blacks' 34-17 triumph over Australia.
Williams said he felt sorry for the youngster.
"Hopefully (the medal) made it a night to remember for him," the All Blacks centre said. "It's better that he has it rather than having it hang up at home."
The official Rugby World Cup Twitter account showed a picture of Williams giving his medal to "a young fan". It did not say why, however.
Williams came on as a half-time replacement for Conrad Smith and had an immediate impact.
He set up Ma'a Nonu for a try to push the All Blacks to a 21-3 lead.
"I knew that I'd been playing some really good football this tournament," Williams said.
"I knew that I was going to be getting some game time so when I got on there I just tried to bank on my preparation and just try and add something of value. Thank God it came off."
Australia pulled it back to 21-17 but Williams said this was the time to dig in and force a victory.
"I just don't want to lose. I just try and stay in the moment and do that job as best I can. In sport, you're going to have a winner and a loser and thank God we were winners.
"At 21-17 the bounce of the ball went our way and we scored a couple more tries.
"It's a very happy changing room because it's like a brotherhood and we all do it for each other," he added.
Captain Richie McCaw, fly-half Dan Carter and centre Nonu are among the All Blacks for whom the World Cup final was their last appearance for New Zealand.
"We've got some special men leaving us but it just shows how good our roster is, with the depth of players that we have in our squad -- all of us contribute," Williams said.
"It wasn't spoken too much about in the week but we knew we had to see those guys out winners. It was just a special night, not just for those guys but for everyone because we all pulled our weight."
