Read Marriott's filing from yesterday. They lay out the timeline according to them. The incident was Sunday, the accuser reported it on Monday morning, Marriott interviewed the accuser, reviewed video and determined Mike should leave the hotel but didn't tell him. They then called the NFL on Monday, the NFL sent their investigator on Monday night to interview the accuser, review the video, and then called other NFL personnel who came to tell Mike he had to leave and escorted him out at about 10pm Monday.
They also state that the NFL decided to remove Irvin from coverage on Tuesday and then Mike went on the radio on Wednesday morning. They also pointed out the drinks comment about not remembering and that the only touching was a handshake.
