I think it was over for the hotel but not the NFL. We do not know the background with Irvin and the NFLN and what might have transpired close to this event.
The NFL will be supported by that call in Irvin made outing himself. That, was more than enough to get him off the air. They can say they didn't know which party to believe but once Irvin made it public, their chosices were few. Think they're putting him back on the air with all of the owners in town? NFLN execs would have been out of a job and deservedly so.
And since no claim has been made of lost money from the NFLN by Irvin, what was his punishment? Being sent home but he outed himself and broke his own story, the dumbest move in all of this.
