(Victor Valenzuela and Krazy Horse.)

Charles “Krazy Horse” Bennett — the unhinged lightweight journeyman who is scheduled to fight at EliteXC’s “Street Certified” event on February 16 — was arrested yesterday for domestic assault. His arraignment is scheduled for today, and he has already been replaced on a King of the Cage card that will happen this Thursday; Bennett was booked to fight Victor Valenzuela, who will now be facing Matt Ver Halen. Bennett was supposed to fight Valenzuela at an EliteXC/Strikeforce event in June of last year, but that fight was also canceled after Bennett was arrested on charges of assault and false imprisonment. His status for next month’s “Street Certified” card has not yet been determined.

Bennett has actually been arrested many, many times before on drug and assault charges. But no matter how times cuffs are slapped on the Horse, his happily-go-lucky spirit is never broken. For proof, check out this compilation of all his smilin’ mugshots (skip past the first 0:28), and watch ’til the end for his special message to the kids:

The good news for EliteXC is that they’ve found an opponent for heavyweight rising star Antonio “Bigfoot” Silva on the “Street Certified” card. Silva — who EliteXC live events prez Gary Shaw has claimed “could knock out any heavyweight in the UFC” — will face former UFC champ Ricco Rodriguez; both men have previously fought as super-heavyweights. Speaking of drugs, Rodriguez makes his first appearance on VH1′s Celebrity Rehab this Thursday at 10 p.m. ET.
