Like the other major sports leagues in the United States, the NFL maintains protocol for a disaster draft. In the event of a 'near disaster' (less than 15 players killed or disabled) that caused the club to lose a quarterback, they could draft one from a team with at least three quarterbacks. In the event of a 'disaster' (15 or more players killed or disabled) that results in a club's season being canceled, a restocking draft would be held. Neither of these protocols has ever had to be implemented.
