Rice and his fiancée, Janay Palmer, were both arrested for simple assault after an incident early Saturday at a casino in Atlantic City, N.J.
Rice and Palmer "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 Palmer 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 in the video posted Wednesday 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," Diamondstein said.
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.
Rice's court appearance originally scheduled for Tuesday was postponed, and 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.
The incident will be reviewed by the NFL under the league's personal conduct policy.
