The Expendables star was initially arrested on suspicion of assault with a deadly weapon after clashing with the fellow gig-goer at the Rose Bowl in Pasadena, California.

The Los Angeles County District Attorney declined to pursue felony charges, but last month (Aug15), city prosecutors pressed forward with counts of misdemeanour assault and battery.

Ortiz appeared before a judge on Thursday (08Oct15) and entered not guilty pleas for both accusations, reports TMZ.com. He is due back in court next month (Nov15) and, if convicted, faces up to two years behind bars.
