"I called Coach (Doug) Meacham and Coach (Mike) Gundy and I committed to Oklahoma State," said Lampkin on Friday evening. "They were excited and I will be up there for the spring game tomorrow."
Lampkin becomes the sixth known commitment in the Cowboys 2012 class and he is the first bonafide defensive back.
Besides Oklahoma State, Lampkin said he was recruited by TCU, Texas A&M, Texas Tech, Baylor, Kansas State, SMU, and North Texas.
