The Miami Police Department report released Thursday does not charge Kaepernick with any crime. The woman told police that on April 1, Kaepernick undressed her in a bedroom and left.
The report says 49ers wide receiver Quinton Patton and Seattle Seahawks wide receiver Ricardo Lockette were also in the apartment.
The woman told police after Kaepernick left, the two others peeked inside and she ordered them out. The report says she doesn't remember anything after that and woke up in a hospital.
The 49ers say they are aware of the incident. Kaepernick's agent didn't immediately respond to an email and phone call seeking comment.
