We admit it - you couldn't pay ZOO £5m to step into the ring with Joe Calzaghe. Luckily, that's where American boxing legend Roy Jones Jr comes in - as he's set to pocket that sum for this weekend's light-heavyweight fight in New York's Madison Square Garden, against the self-styled fighting pride of Wales.

And ZOO can reveal the pounding that's set for Jones Jr's unfortunate bonce!

New DVD, Joe Calzaghe - My Life Story takes us inside the ring for a one-off pads session between the former undisputed super-middleweight world champion and his dad/trainer, Enzo. During the two-minute clip Calzaghe Sr wears a headcam to capture the speed and power of his 36-year-old son's punching.

My Life Story, out on 10 November, charts the Calzaghe story, from Sardinia to Las Vegas, via Newbridge, Wales. And with the tough Taff set to quit boxing after his clash with Jones Jr - which starts at about 3am on Sunday morning, UK time - it's worth watching the pound-for-pound world No3 try to finish his career on a high. Go Joe!
