Ray Rice knocked fiancee out

— -- Baltimore Ravens running back Ray Rice struck his fiancée with his hand, rendering her unconscious, according to a summons obtained by ESPN.

Rice and his fiancée were both arrested for simple assault after an incident early Saturday at a casino in Atlantic City, N.J. Rice and the woman "struck each other with their hands," according to an Atlantic City police report.

A video obtained and posted online by TMZ on Wednesday shows Rice lifting the woman by her arms out of an elevator at the Revel Casino and laying her on the ground. She appears limp as he pulls her legs away from the elevator doors and later props her up.

Rice's attorney, Michael Diamondstein, told The Baltimore Sun that the footage is authentic but incomplete. 

"The video that has been put up by TMZ shows the very end of what transpired between Ray and his fiancee," said Diamondstein, who said he and Rice would "not try this case in the media."

The prosecutor's office released a statement, saying the domestic violence incident involving Rice has been referred to the Atlantic County Prosecutor's Office for review.

The incident will be reviewed by the NFL under the league's personal conduct policy.

Rice's court appearance originally scheduled for Tuesday has been postponed. The new date has not been set.

The postponement comes after the police department requested the prosecutor's office to get involved in the case.

Also, Ravens nose tackle  Haloti Ngata has been chosen to replace Rice at the Maryland Society for the Prevention of Cruelty to Animals' kickoff party on Friday night for its annual March of Animals event.

An spokeswoman for the organization said it was a mutual decision because the two sides didn't want to take the focus off the animals and the cause.
