Beng a bit lazy there Primo you could just go to youtube and search.

Iv just done it for you. This clip shows the KO but the original clip showed about 30 seconds of sparring prior to the KO. Looks like its been taken down.

Apparently this was an experienced unlicenced fighter and someone has suggested its something like a dig at Blackwell as he was fighting unlicensed before he turned pro.
