The 6-foot-7 freshman from Macon, Georgia, posted a picture of himself in a Tigers uniform on Twitter with "Committed" across the image.
Moore was considered a top-60 college prospect coming in from Westside High, but played only two minutes as he continued to rehab a leg injury from his final prep season. Texas Tech, which reached the NCAA championship game before losing the title to Virginia, had planned to apply for a medical redshirt for Moore.
Clemson will also have that option. Moore would have to sit out a year due to NCAA rules before playing for the Tigers.
