Michael Irvin is being investigated for allegedly sexually assaulting a woman at a Ft. Lauderdale hotel ... something he vigorously denies.
Law enforcement sources tell TMZ Sports, a 27-year-old Florida woman filed a police report, claiming she and the NFL Hall of Famer were out at a bar in the early hours of March 21 when they went back to the W hotel, where Michael was staying.
The woman says they were in Michael's room when she began to feel sick. She says the last thing she remembers is fighting him off.
