The NFL announced Monday that the 2018 supplemental draft will be held on Wednesday, July 11 at 10 a.m. PT.
If a team selects a player in the supplemental draft, it loses its pick in that round for the following year's draft. Eligible players who go undrafted become free agents.
Current Seahawks offensive tackle Isaiah Battle is the most recent player selected in a supplemental draft, having been taken by the St. Louis Rams in the fifth round in 2015. He is one of three current players to come into the league via the supplemental draft along with New York Jets receiver Terrelle Pryor (2011) and Cleveland Browns receiver Josh Gordon (2012).
The Seahawks have picked in the supplemental draft only twice. Seattle picked Notre Dame running back Al Hunter in the fourth round in 1977, making Hunter the first player to come into the league via the supplemental draft. Then in 1987, the Seahawks picked Oklahoma linebacker Brian Bosworth in the first round.
