Angle Injury

Does anyone know the details on what exactly happened in the main event? Kurt Angle genuinely picks up a concussion early doors as far as I know and he gets wheeled off. I remember watching it at the time and we were trying to figure out whether it was part of the storyline of real.

So I was wondering does anyone know what the original plan for the match was? Was Kurt supposed to be hurt from the pedigree on the table anyway or was he supposed to be down for a few minutes and just back in the match as normal?

I watched it again last night and I think it's terrible they sent him back out with a concussion. That could have really messed him up. Having said that, from a 'show' point of view, it looks like they handled it really well.

So yeah does anyone know what was supposed to happen if Kurt hadn't got the injury?
