Under the NFL's new collective bargaining agreement, teams can no longer forgive fines, and Watson would have been fined $50,000 for every day he was absent from camp.
Watson still wants to be traded by the Texans -- a stance that has remained unchanged since the start of the offseason, sources told ESPN.
Watson first asked to be traded in January after the Texans hired Nick Caserio as their general manager.
Less than two months later, the first of 23 lawsuits was filed against Watson. The now 22 active lawsuits allege sexual assault and inappropriate behavior against the Texans quarterback.
Since the lawsuits were filed, new head coach David Culley has largely avoided addressing the allegations against Watson, other than referencing a letter sent by Texans ownership to season-ticket holders in April that said, "We want to assure you that we take these allegations very seriously."
