haha it also happened too Kevin Randleman in UFC, fell over on the ring walk and the fight got cancelled at the last second. Everyone was fuming and in disbelief, it was UFC 24 I believe.
I have that event on some bootleg DVD, because after UFC 22 they stopped releasing the VHS and DVDs, until UFC 30 and it started again. but UFC 23-29 was in the dark period and underground
I brought that DVD in around late 2000 from a market, and was absolutely disgusted and fuming waiting for the main event, it was taking ages too because the DVD was recorded from the PPV, and not edited or cut.. so it was in real time lol, the wait was awful.

I was a big fan of Pedro Rizzo as well and wanted to see the fight so badly.
