1. The Atlanta Beat had traded its second round pick in this draft to the San Diego Spirit for Kerry Gragg as the sixth round selection in the main draft.
It was intended that the supplemental draft would facilitate: "selection of players who just completed their college eligibility or who recently submitted their names into the draft pool". After it had taken place, each team had four additional players on a provisional roster of 24. This would be cut down to 20 before the season began.
Draft host Tony DiCicco reminded disappointed candidates who were not selected that each team would still hold open try-outs before their rosters were finalized: "the process is not over". He said that an agreement on WUSA's formal affiliation with the USL W-League and Women's Premier Soccer League was close.
