11:57 AM PT -- A rep for Banks tells TMZ Sports the allegations are simply not true -- adding, "Evidence exists that proves this false."
Ex-NFL player Brian Banks -- who was famously exonerated in a previous rape case -- is facing new allegations of sexual assault in a lawsuit ... TMZ Sports has learned.
Banks is being sued by a woman who claims the former Atlanta Falcons player hired her to clean his apartment in Feb. 2018 -- and while she went to work, he pulled out his penis and started masturbating in front of her.
In her suit, the woman claims Banks showed her porn on his computer and asked her to join in -- and when she refused, he got up and started forcing himself on her.
The woman claims Banks forcefully kissed her breasts and began groping her butt. She also claims Banks forced her to touch his penis while she "repeatedly" asked Banks to stop and let her go.
Eventually, the woman left -- and now she claims she was so traumatized, she can no longer clean homes out of fear she might be assaulted or raped.
She's suing Banks for $10 MILLION for assault, battery, false imprisonment and intentional infliction of emotional distress.
We reached out to Banks for comment -- so far, no word back.
Brian's story is famous -- he was a high school football phenom when a classmate accused of him of rape in 2002. He eventually served 5 YEARS in prison.
But, after he was released, the accuser admitted she LIED -- and a judge overturned the conviction in 2012.
Banks resumed his football career and even signed a contract with the Falcons in 2013.
His story is being made into a movie that is scheduled to premiere in August 2019.
