Moore, from Macon, Georgia, played in only one game for the Red Raiders due to injury. He enrolled at Clemson this past May and has practiced with the team, including playing in the Tigers' run to the gold medal at the World University Games this summer.
Moore was considered a four-star prospect out of high school, and ESPN had him rated No. 43 in its top 100.
The Tigers hope Moore will add some height and athleticism to the middle following the loss of 6-9 forward Elijah Thomas.
