He's getting at least a 24 game suspension
I doubt they'll actual go that far.
They smart play here is to use the indefinite suspension move. For everyone who doesn't follow football and is just following this story, it looks like they hit him with some real shyt. For those that follow the game, we'll recognize that "indefinite" really just means "one full season, as long as you don't fukk some other shyt up before next training camp".
That clause where indefinitely suspended players have to apply for reinstatement is automatic redemption story bait. All Watson has to do is keep it vanilla in his sex life for a year or so, and have some light reading memorized for his interviews he does around his reinstatement to appear contrite, and this is likely the end of it, assuming no other fukkery occurs.
