"Today is the day that I'm actually qualified," Jackson (Klein HS) told the world in a Twitter update.
The 5-foot-10, 175-pound corner was an Army All-American a year ago. He finished his senior year with 73 tackles and three interceptions, despite most teams throwing away from the Texas product.
"I'm just glad I made the right decision and kept hanging in there," Jackson told Big Red Report late Tuesday night. "I'm ecstatic."
Fox Sports will have more on the breaking news on Wednesday, but until then, here is a scouting report from National Recruiting Analyst Greg Powers.
"There has never been any doubt about Jackson's ability to be an aggressive defender who will come up from the corner spot and make sure tackles and with his size and long arms. There was some concern about him being able to be the type of player you could put on an island and let him lock down the other team's best receiver one-on-one and he answered those questions by dominating at the U.S. Army Bowl." - Greg Powers
