Why don't we ever see injuries or blood on The Jerry Springer Show?

You’d think with all the fighting that occurs we’d see the occasional bloody nose or even a broken arm or leg. After watching this show for 20 years (hey, I like seeing ridiculous people make fools of themselves, sue me) I’m pretty sure I’ve never seen anyone get injured. Any thoughts? And please don’t suggest all the stories are fake and they’re just a bunch of actors – some possibly, but definitely not all.
