STILLWATER — Oklahoma State’s search for its next defensive coordinator might or might not be finished. On Sunday evening, GoPokes.com reported that Dallas Cowboys linebackers coach Reggie Herring had accepted an offer to be OSU’s new defensive coordinator. But within an hour of posting the initial report, the Web site had amended it, citing sources who both confirmed and denied that Herring had taken the job. The Dallas Morning News reported Sunday night that Herring had interviewed at OSU, but no formal agreement had been reached. Attempts to contact Herring on Sunday were unsuccessful. Oklahoma State associate athletics director for media relations, Kevin Klintworth, said that he could not confirm an offer to any candidate Sunday night. Herring, who was a candidate for the same job two years ago when Tim Beckman was hired, worked at OSU as a graduate assistant, then linebackers coach from 1981-85. Herring has been a defensive coordinator at Arkansas, North Carolina State — where his squad once led the nation in total defense — Clemson and TCU. He has three years of experience coaching linebackers in the NFL with Dallas and Houston.
