According to WRAL Sports Fan...
Smith only registered four points in six minutes in the win over East Carolina on Wednesday night before leaving with pain in his left knee.
Head coach Sidney Lowe said Smith injured the knee while going for a loose ball. And now Smith has returned to Raleigh to have it examined by N.C. State's orthopedic staff.
Smith's injury will likely have the Pack start a frontcourt of Richard Howell and CJ Leslie in their game tonight against George Mason. The Pack's game tips off 6 ET and will be televised on ESPNU.
