The ex-Ohio State cornerback -- and projected 1st round NFL Draft pick -- just issued a statement denying the claims in a police report filed in Cincinnati ... and says the accuser is trying to ruin his life.

"The allegations against me concerning the night of April 8/9 that have recently been reported in multiple media outlets are completely false."

"I did not commit a crime and have not been charged with a crime."

Conley says he prides himself in doing things "the right way" -- adding, "The things being said about me and what happened that night are not true and don’t fit my character at all."

"I realize that I put myself in the situation and I could have used better judgment. However, I have worked tirelessly to put myself in position to have the honor of being an NFL draft pick and these untrue allegations are putting a huge cloud over my name and the NFL Draft."

"These allegations appear to be an attempt to ruin this once in a lifetime experience for me and my family."

"There were several witnesses, including another female, who were present the entire time and have given statements that give an accurate account of what took place. We also have video evidence that further discredits and disprove other versions of these events. I am upset but realize that I am powerless when false accusations are made and people try to convict you in the court of public opinion. It’s sad that your name can get dragged through the mud based upon untrue and malicious allegations alone."

"I am completely confident that as the facts actually come out my name will be cleared."

"I was excited about participating in the Thursday’s draft but I have decided that i would be selfish for me to stay and be a distraction to the NFL, the other players and their families who have worked just as hard as me to enjoy the experience so I will not be in attendance."
