Miami Dolphins linebacker Koa Misi pleaded not guilty to three felony charges in connection with an incident last year at Isla Vista, Calif.
Kisi was accused of breaking through a door of an apartment and punching a man in the face.
The 25-year-old Misi has been charged with battery with serious injury, residential burglary and dissuading a witness.
He was arrested in Florida last month after never showing up for his arraignment for the April 2011 attack, which his attorney called a drunken altercation.
In his two seasons with the Dolphins, Misi has 75 tackles and 5.5 sacks.
