Virginia linebacker Ahmad Brooks, Texas fullback Ahmard Hall, Iowa State defensive end/linebacker Jason Berryman and Hutchinson (Kan.) Junior College linebacker Dave Dixon have gained entry to the NFL supplemental draft on July 13, according to the league's player personnel office. Brooks and Hall have workouts scheduled for Thursday. Dixon's pro day will take place next Monday at Westbrook High School in Beaumont, Texas, where already seven teams are planning to send a scout. Players have until June 30 to submit paperwork for review by the NFL's player personnel department, and they cannot schedule "pro day"-type workouts until their applications have been approved.
