Brown, a 6-foot-3 forward from Australia, averaged 6.4 points and 6 rebounds for Washington State this past season. Brown will be eligible to play for Tennessee in 2018-19.
Tennessee coach Holly Warlick said in a statement that Brown "has great size, can stretch the floor with her shooting range, can shoot over the top of defenders, gets on the glass, runs the floor and plays well without the ball."
Brown boosts a roster lacking experience following the departures of WNBA second-round draft picks Mercedes Russell and Jaime Nared. Tennessee's top five scorers this season were Russell, Nared and freshmen Rennia Davis, Anastasia Hayes and Evina Westbrook.
