Taylor and Brown had been engaged in settlement talks for months, per Folwer but “agreed their communication would remain confidential” until the filing of Taylor’s lawsuit. This is how neither the Raiders, nor the Patriots knew of the allegations. By all accounts, the NFL was also unaware.
The NFL can place Brown on the commissioner’s exempt list but it appears he is set to play on Sunday against the Dolphins. That could change following the NFL’s meeting with Taylor next week as they look to gather as much information as possible about the allegations.
