The woman who claims Gareon Conley raped her at a Cleveland hotel last year has filed a lawsuit against the Raiders player ... claiming she was mentally and physically hurt during the alleged incident. FYI, Conley -- 22 years old -- was never arrested or charged with a crime ... and adamantly denies any wrongdoing. In the lawsuit -- filed earlier this month in Cuyahoga County Court in Ohio -- the accuser alleges Conley "physically touched and engaged in the sexual contact" and "sexually assaulted, battered and raped" her after meeting and partying at a nearby bar.
