None of the four eligible players were taken in the NFL's supplemental draft Thursday.

League spokesman Michael Signora says in an email that all four players -- New Mexico receiver Chase Clayton, North Carolina linebacker Darius Lipford, Virginia-Lynchburg defensive tackle LaKendrick Ross and SMU running back Traylon Shead -- went undrafted and are now free agents.

The supplemental draft allows qualified underclassmen who did not request early entry into the regular draft to have a chance at entering the NFL. Teams submit picks and are awarded players if their bid -- for which round they would take that player -- is highest. Teams then lose the corresponding pick in next year's draft.
