Man, nice freaking card. Looks like it had a four-man heavyweight tournament as well, some female fights, and Nate Marquardt pummelling someone named Steve Gomm into submission. The HW winner's name is Tom Sauer too. I bet he tricked the other fighter into whitewashing the ring, and then beat the hell out of him when he went for a drop cloth. That's what I'd do.
