Four days after Georgia declared him academically ineligible for his senior season, King issued a statement through the athletic department saying, "I look forward to pursuing an opportunity at the next level through the NFL's supplemental draft and playing the game that I have loved since I was a young boy."
Eligibility for the draft is determined "on a case-by-case basis," according to NFL spokesman Greg Aiello.
Former Georgia cornerback Paul Oliver also was academically ineligible in 2007 and entered the supplemental draft. San Diego selected him in the fourth round, surrendering an equivalent pick in the 2008 draft.
The only other player known to be entering this year's supplemental draft is former Ohio State quarterback Terrelle Pryor.
Pro Football Talk reported that King received a sixth-round grade from the NFL scouting service BLESTO. Rob Rang, senior analyst for NFLDraftScout.com, also thinks King has late-round talent, but that doesn't mean he'll be drafted.
"While talented enough for teams to consider using a draft pick on, King has his work cut out for him if he going to be able to convince a club he has the work ethic and maturity worthy of a selection in the supplemental draft when there are several other similarly gifted backs who will be available for signing as undrafted free agents," Rang wrote. "Teams will ask themselves why give up a pick for King when they could sign Auburn's Mario Fannin, Miami's Graig Cooper or Virginia Tech's Darren Evans (among others)."
King rushed for 1,271 yards in three seasons at Georgia, but he never lived up to the expectations when he was Georgia's highest rated in-state signee in the 2007 class.
Last season he served a two-game suspension for failing to appear in court for a speeding ticket and missed Georgia's bowl game for missing a fifth academic appointment.
King has also considered playing in the Canadian Football League or transferring to another school.
