"Yes sir, I committed to Alabama," he confirmed to BamaMag.com on Monday evening while still in Tuscaloosa for an unofficial visit.
Warmack, who attends Atlanta (Ga.) Mays High School, became the first offensive lineman on the commitment list for the 2015 cycle.
FOX Sports NEXT/Scout.com projects Warmack as an offensive guard at the next level based on his current film and listed 6-foot-2, 290-pound frame.
"I feel so comfortable there," Warmack told Scout after receiving the UA offer after a camp performance on June 15. "I have been around there so much, I know everything about the school, we all know each other at Alabama."
BamaMag.com will have much more on this breaking news shortly.
