While UFC let Angle's storyline "open challenge" to anyone from a 4-, 6- or 8-sided ring go unaddressed, it will not be doing that in the future. If WWE attempts to put one of its wrestlers over as superior to MMA fighters, it will respond to put public pressure on WWE to make the match happen.

"Now that we have exposure, we're not going to be ignoring stuff like this. We'll go public and have Chuck Liddell accept any public challenges or claims they'll make," the source said.
