The NFL will not hold a supplemental draft this year. Tom Pelissero of NFL.com broke the news via Twitter:
The NFL just informed clubs it will not conduct a supplemental draft this year, per source.— Tom Pelissero (@TomPelissero) July 1, 2020
The Collective Bargaining Agreement gives the NFL the option to hold a supplemental draft each year, but it is not mandated.
Under the CBA, the NFL may elect to hold a supplemental draft each year. The matter was discussed with the NFL Management Council Executive Committee, and in light of current conditions, the decision was made not to hold one.— Tom Pelissero (@TomPelissero) July 1, 2020
The draft provides an opportunity for players to be drafted, who were not eligible to enter the spring draft. If a team drafts a player, they will forfeit the corresponding pick in next year's NFL Draft. For example, if a team selects a player in the fourth round of the supplemental draft, they will lose their fourth round pick for the next NFL Draft.
Safety Jalen Thompson was the lone player selected in the 2019 supplemental draft; he was selected by the Arizona Cardinals in the fifth round. Past supplemental draft picks include Cris Carter, Ahmad Brooks, and Josh Gordon. The Baltimore Ravens have elected to make a supplemental draft pick only once, when they took offensive tackle Jared Gaither in 2007.
