While still on his official visit in Auburn on Sunday, he announced via twitter: "This will successfully end my recruitment. I am an Auburn Tiger."
"I haven't felt this light on my feet in a while," Lawson said. "The weight of the world is off my shoulder. WDE."
The Under Armour All-American made 82 tackles as a senior with 36 tackles for lost yardage with 26 1/2 quarterback sacks.
Lawson made the official visit to Auburn this weekend with a large group of family members.
The 6-3, 255 defensive end originally committed to Auburn last March as recruiting attention blossomed as he made 87 tackles with 15 quarterback sacks as a junior. Explaining his decision at that time, said, "I really like Auburn and they have been my favorite for a while now. I have a long checklist of things I am looking forward in a college and Auburn meets all of them."
