LSU head coach Ed Orgeron says he NEVER knew of alleged Derrius Guice sexual assault ... insisting a report to the contrary is "completely false."
As we previously reported ... 2 former LSU students told USA Today Sports that the former Tigers superstar RB raped them at their own apartments after nights of heavy drinking.
One of the women says she passed out on her bed and has flashback memories of Guice assaulting her.
She also says it was all particularly troubling because her boyfriend at the time was Guice's teammate on the LSU football team.
