Jackson, a 6-foot-9, 210-pound power forward, selected the Spartans over Maryland, Purdue, Georgetown and Notre Dame.
Jackson is regarded as the No. 29 overall prospect and the No. 5 power forward in the 2017 recruiting class.
Through 21 games in the Nike EYBL, Jackson averaged 15.7 points and seven rebounds a game, while shooting nearly 40-percent from three on 81 attempts.
This is Tom Izzo's first pledge of the class.
