I imagine a handy kid from the street would smash either out of the ring.
It happened to Ricky Hatton, got his arse handed to him off a local nutter in the ‘Railway Pub,Newton’ a few years back.
Boxing and street fighting are quite different, not sure what you’d call the Fury/Klitschko fight,
They looked more like to drunks outside a kebab shop after a session on the beer.
