Not the roster/workout bonuses. Those were based on him not being suspended. As for the 1m signing bonus... I have no clue.
If the suspension stands (assuming no long drawn out lawsuit, which I actually expect), this would put the cap figure around 19 to 19.5m I believe, including Brees's franchise tag cap figure. If there ends up being no lawsuit and the suspension stands... I expect his deal to get finalized pretty soon.
