The school announced both additions Tuesday. Bello will be eligible to play for ETSU this season as a graduate transfer. Glass must sit out the 2015-16 season because of NCAA transfer rules.
Bello began his career at Baylor, where he played two seasons. The 6-foot-4 guard averaged 1.8 points, 1.1 rebounds and 10.9 minutes for Missouri last season.
Glass averaged 2.1 points and 1.1 rebounds in 19 games last season for Wichita State, where current ETSU head coach Steve Forbes was working as an assistant. Glass, a 6-8 forward, also played for Forbes at NorthwestFlorida Community College.
