SAN JOSE, Calif. >> San Francisco 49ers linebacker Reuben Foster pleaded not guilty today to charges stemming from allegations that he attacked his then-girlfriend in their home in February.

A preliminary hearing has been scheduled for May 17, at which point Foster’s former girlfriend, Elissa Ennis, may testify under oath.

Ennis has recanted the allegations that led to the domestic violence case. Foster has been charged with domestic violence with an allegation that he inflicted great bodily injury, forcefully attempting to prevent a victim from reporting a crime, and possession of an assault weapon.

The 28-year-old woman initially told police that Foster dragged her by her hair, physically threw her out of their house, and punched her in the head eight to 10 times. She later issued a statement through her attorney saying her injuries were the result of a fight with another woman.

Prosecutor Jim Dermertzis has said the district attorney’s office will continue to prosecute the case against Foster even if Ennis does not cooperate with the investigation.

If convicted of all charges, Foster could face up to 11 years in prison. Foster remains a member of the 49ers although the team hasn’t allowed him to participate in the offseason program while his case is ongoing.
