The 6-foot-1, 182-pounder became the Mocs' 16th commitment for the 2016 signing class. Commitments are nonbinding until letters of intent have been signed.
National signing day is Feb. 3.
Lawson was a first-team Class 3A all-state selection in 2015 and made the Dothan Eagle Super 12 team. He chose the Mocs over offers from Football Bowl Subdivision programs Memphis, Middle Tennessee State, Georgia Southern, Arkansas State and Southern Mississippi.
"I liked the campus and how the coaches had a nice relationship with the players," Lawson said Saturday. "The coaches talked about the winning tradition and how they want us to come back and start on a four-peat (of conference titles)."
Lawson also plays basketball for Pike County and in the spring will double up with baseball and track. He said it's been "a while" since he has focused on one sport.
On the football field, he had 114 tackles in 11 games in 2015 and has the reputation as a hard-hitting safety.
"I'll catch the ball every time you throw it my way," he said, "but if you're running wild, I'll clean your clock."
