Actually, there was this one NASTY injury that happened during the Slamball tryouts special they aired in the beginning of the second season. Some guy jumped on a trampoline and while landing, his foot got caught in between this small hole between the trampoline and mat in the middle. As he fell to the side, his viscously broke his ankle and from what I remember, I think his ankle just ripped apart and almost broke his foot off. Although my memory may be a little off, that's how I remember it. It was VERY a gruesome injury.
Anyways, speaking of Slamball, I do wish it comes back. It entertained me, and I liked it. What else does Spike TV have to offer anyways besides VIP and other old shows' re-runs?
