USC's Jefferson leaving school for NBA Draft

Davon Jefferson, despite claiming otherwise last month, will enter the NBA Draft, a source close to the Southern California standout told CBSSports.com on Saturday.

An official announcement is expected soon.

Jefferson averaged 12.1 points and 6.3 rebounds per game this past season. The source said Jefferson will sign with an agent -- meaning he is not merely "testing the waters" like some college players, meaning USC is now guaranteed to lose its top two scorers from a 21-win team given how O.J. Mayo has already declared.
