NORMAN — Oklahoma coach Bob Stoops said freshman defensive tackle Du’Vonta Lampkin still hasn’t been released from the National Letter of Intent he signed with Texas, and that Texas still hasn’t denied Lampkin admission into school.

Lampkin, who committed to the Sooners in November 2013 and then decommitted the next summer, signed with the Longhorns on national signing day in February, but two days after that, UT defensive line coach Chris Rumph left for Florida.

Lampkin, a Houston native, announced at a summer news conference that he couldn’t satisfy Texas’ foreign language requirement so he would be attending a different college.

The National Letter of Intent guidelines state that the letter is “declared null and void if you have a written denial of admission,” but Stoops said Monday that Lampkin hasn’t received a denial letter, and Texas coach Charlie Strong has said he won’t release Lampkin.
