Knox's only current scholarship offer is from Oklahoma, where his former Gibbs teammate Gary Simon is a freshman cornerback.
In three 2012 games, Hall had scored two touchdowns on offense and had a 12-tackle performance on defense.
Knox had expected more offers to begin pouring in before the shooting, which cost the 6-foot-2, 180-pound Hall the rest of his junior season.
Knox said he expects Hall to recover in time for spring football practices.
SANTA FE'S HARDING REMAINS OPEN
Khari Harding doesn't have an Oklahoma offer, but he'll watch the Sooners play in two weeks at Texas Tech.
Harding, the Edmond Santa Fe senior safety and Arkansas commit, will take an unofficial visit to Lubbock, Texas, on Oct. 6 for the game against the Sooners.
“I'm just gonna go down to Lubbock and see what they have to offer,” Harding said after the Wolves beat Southmoore 53-37 at Wantland Stadium on Thursday.
The Red Raiders haven't offered Harding a scholarship yet, but could this weekend. Harding has yet to take any of his five official visits.
The 6-foot-1, 205-pound safety said he's still committed to the Razorbacks but wants to keep his options open, especially with a new coach all but assured to take over after this season. The Razorbacks have also struggled on the field — Arkansas suffered an upset loss to Louisiana-Monroe and a 52-0 home loss to No. 1 Alabama.
“It was pretty tough to watch,” Harding said of the Alabama game.
The physical, hard-hitting safety has an increasingly long list of offers, which includes Oregon State, Arizona State, Iowa State and Kansas State, among others. He most recently picked up an offer from new coach Mike Leach and Washington State.
His primary Washington State recruiter is former OU receiver Jarrail Jackson.
None of the state schools — OU, Oklahoma State or Tulsa — have offered Harding scholarships.
