Surprised that I haven't seen anyone else backing up your version, but there are plenty reports and quotes about it being accidental. Almost as if you've got some sort of anti-Considine obsession.
And I don't know about Brown , but if it was me that got knocked out cold and I didn't know what had happened , I'd probably ask my team-mates and manager and maybe some of the spectators that I knew had been there , if they could tell me. Or are they all in on the big cover-up too ?
