LAS VEGAS — Former NFL star Darren Sharper pleaded guilty in Las Vegas to a reduced charge of felony attempted sex assault as part of a four-state plea deal that’ll send him to federal prison for about nine years.

Sharper appeared Tuesday by Internet hookup from a courtroom in Los Angeles before a Clark County District Court judge who accepted his plea and scheduled sentencing June 25.

A plea agreement calls for Sharper to serve his 38 months to eight years in prison for the Nevada conviction at the same time he’s serving sentences from California, Arizona and Louisiana.

On Monday, the 39-year-old Sharper pleaded guilty to sexual assault in Arizona and no contest to raping two women he drugged in Los Angeles.

Sharper is due in federal court in New Orleans on April 6.
