Cant tell you what its like to get knocked out in the ring but ive been knocked out a fair few times when i used to ride bmx's and downhill moutain bikes etc. Once i got knocked out cold for about 3 minutes and couldnt rememver anything from about 5 minutes before the impact to when i woke up. It doesnt hurt a bit because obviously part of your brain is basically shut down so you cant feel it, hense why some people will pass out during intense pain. You'll probably have a nice little dream or dream that somebody else is there and when you wake up you'll be a bit disorientated for a few seconds but thats all there is too it.

Bottom line is, dont think about it. If you think about getting knocked out that's where your concentration will be and theres only one plsce youll be headed when that happens...on the canvas,

Cheers
