This afternoon WWE sent out a message to their subscribers of their Mobile Alert system stating that Kurt Angle has issued an “open challenge for One Night Stand to anyone from any brand”.

The message then goes on to say that he doesn’t care if the person is from a 4-sided, 6-sided, or 8-sided ring”.

The Challenge was initially made last night on SmackDown!

The WWE owned "brands" of Smackdown, RAW, and ECW all use 4-sided rings. TNA uses a 6-sided ring, and UFC uses an 8-sided caged ring.
