The alleged attack at the couple's Shore Club hotel room in Miami Beach early Saturday occurred after they had been partying at the venue.
The unidentified woman also told police she was sleeping when Sapp pulled her out of bed and demanded she leave the room.
Sapp, a former star with the Tampa Bay Buccaneers and Oakland Raiders, was charged with misdemeanor domestic battery after both parties were questioned by police.
Sapp was released from the Miami-Dade County jail Saturday evening.
He was in Miami to provide TV commentary Sunday for the NFL Network at Super Bowl XLIV between Indianapolis and New Orleans, but The Miami Herald said he has been taken off the air until the network reviews the incident.
