Plavsic graduated from Hamilton Heights Christian Academy in Chattanooga before redshirting with Arizona State last season. Plavsic is originally from Ivanjica, Serbia, but moved to the United States in October 2017.
In a statement, Vols coach Rick Barnes said Plavsic is “a strong, physical player who can hold his own in the paint, and his offensive skill set could allow him to play away from the basket, keeping the floor spaced.”
Plavsic plans to enroll at Tennessee for the first session of summer school.
UT athletic department spokesman Tom Satkowiak said Plavsic will seek an NCAA waiver enabling the 7-foot center to play immediately. Because Plavsic isn’t a graduate transfer, he would have to sit out the 2019-20 season if he isn’t granted a waiver.
