A source told Sports Illustrated's Robert Klemko on Thursday that police have yet to release a video that shows Baltimore Ravens running back Ray Rice knocking his fiancée unconscious before dragging her.

Rice was arrested early Saturday morning in Atlantic City, N.J., after what was originally described as a "minor physical altercation" with fiancée Janay Palmer, who was also charged and released in the incident.

According to a summons obtained by ESPN.com after the incident, both Rice and Palmer "struck each other with their hands." Rice knocked Palmer unconscious, according to the summons.

TMZ released a video online this week of what it said displays Rice dragging a seemingly limp, motionless woman out of a Revel Casino elevator.

Michael Diamondstein, Rice’s attorney, told the Baltimore Sunthat the video showed “the very end of what transpired.”
