Oklahoma State recruiting notebook: Khari Harding, Cre Moore and David Cornwell attend OSU-Texas

Topping the list was Arkansas safety commit Khari Harding of Edmond Santa Fe, who was on an unofficial visit.

The Cowboys have not offered the 6-foot-1, 205-pound senior, who is ranked No. 6 on The Oklahoman's Super 30 recruiting list. His uncle, Rodney Harding, was an OSU defensive lineman in the 1980s.

Several Division I programs have extended offers to Harding, who could be ripe for picking from an Arkansas program that is in disarray. The team has struggled this season, most recently a 58-10 loss to Texas A&M Saturday, and the coaching situation is in limbo.

Broken Arrow senior cornerback Cre Moore announced his visit on Twitter. The 6-foot-1, 175-pounder has more than 10 offers from a variety of programs, highlighted by Kansas State and Tulsa.

The Cowboys currently have three defensive backs committed in the 2013 class.

Jones quarterback David Cornwell, a 6-foot-5 junior, was also in attendance Saturday as part of a three-week tour that will have him on trips to Auburn and Michigan the next two weeks, according to Rivals.com.
