It looks like WWE's live event in Springfield, Missouri tonight may be changed. The advertised main event is Ryback vs. CM Punk.

However, Punk just wrote the following on Twitter: "Later today, after not sleeping...I will beat up @mikethemiz You're welcome Springfield Missouri."

It's possible that The Miz vs. CM Punk is on the cards as a future program, or it could just be for tonight's show. Ryback is still scheduled for the event and will likely fight The Shield in some fashion.

More as we get it.
