Yeah, I know he was supposed to be "taken out", but he hit the steps wrong if you ask me, and like you said, hurt his wrist or something. I know it's nothing major, but it just looked weird to me.
Did I mention that I really like that feud?
I went back & checked it out - the ref smacked his left arm on the black retaining wall around the ring when he was falling.
Chuck was actually rehired a while ago, they just didn't have him doing anything for like a year before he started doing the dark matches.
