UFC Hall of Famer Mark Coleman was reportedly upset with CM Punk at last weekend's UFC event.

Coleman was apparently furious that UFC producers showed Punk on camera at the event instead of him. Nothing took place, but those close to Coleman said he was ready to pick a fight with Punk over it.

Punk also attended last night's UFC event on FOX with his real-life girlfriend, Amy "Lita" Dumas. Punk is also set to attend the UFC 159 PPV on April 27 to see his friend Chael Sonnen fight Jon Jones.
