According to Rapoport, Thompson learned yesterday he lost his eligibility for the 2019 season and has since hired agent Brad Cicala to prepare for the NFL.
Tony Pauline reports that Thompson was given a third- or fourth-round pre-season grade by scouts he’s spoken to.
Thompson reportedly wanted to return to Washington State, but the NCAA ruled he was ineligible.
Pauline adds that Thompson will work out for teams on July 8 in Los Angeles.
Thompson is the fourth player to enter the 2019 Supplement draft including West Virginia WR Marcus Simms, Texas TE Devonaire Clarington and Syracuse LB Shyheim Cullen.
The 2019 Supplemental Draft will be held in the coming weeks.
Thompson played three seasons at Washington State. In total, he recorded 190 tackles, six interceptions, 17 pass defenses, two forced fumbles and five recoveries over the course of 39 games.
