Jackson, who also plays safety on the defensive side, was one of the driving forces of last season's state runner-up team.
He had drawn offers from TCU, Texas A&M, Alabama, LSU, Ole Miss, Baylor, Florida, and Oklahoma.
Jackson's commitment ceremony was a pep rally-style event taking place in Boling. The town of more than 1,200 people in Wharton County is still recovering from the effects of Hurricane Harvey.
The ceremony served as a return to normalcy in town as residents endure the damage left by Harvey's flooding.
