Nelson, a 6-foot-1, 200-pound 5-star linebacker from Skyline High in Dallas, Texas had originally planned to sign with Texas A&M.
But after hosting the Oklahoma coaching staff last Thursday night he decided to switch his commitment from Texas A&M to OU at a signing announcement ceremony at Skyline.
"He signed with OU," said one of Nelson's teammates at Skyline. He held offers from coast-to-coast as schools like Oregon, USC, Stanford, North Carolina, Tennessee, Florida, Minnesota, LSU, Nebraska, Texas, Cal and UCLA.
Over the past two seasons he has been one of the most dominating defensive players in the Lone Star State. He compiled 276 tackles, 22 sacks, 38 tackles for a loss and blocked at least eight punts to earn All-State honors in '08 and '09.
