Ken Shamrock and Dan Severn
 

They've had a few classic bouts in UFC, but have they ever wrestled each other in WWE?

Hey that rhymes.

I know on a RAW a few years back there was a Triple Threat Match with those two and Owen Hart...can't think of any other matches they had together in the Pro Wrestling world.

They tagged once in 1998 and wrestled each other two weeks in a row a couple of months later.

They definately worked together in the WWF. I remember them building up Shamrock vs. Severn III and it ended up happening with no hype or need.
