Chael Sonnen is still undefeated ... battery charges against the 44-year-old retired MMA star were dismissed in Las Vegas, TMZ Sports has confirmed.
The American Gangster was slapped with 5 battery citations after an alleged brawl at a Las Vegas hotel the night of December 18th ... where Sonnen was accused of roughing up numerous people.
However, a judge in Nevada dismissed all 5 misdemeanor battery charges against Chael on Thursday.
"This matter was dismissed by the court on its own based upon the fact that the citation’s notice to appear failed to comply with the legal requirements as set forth by Nevada law," the Clark County District Attorney told us when we asked for an explanation.
