From Scottie Wolf:

USC players Vincent Joseph and Alfred Rowe
were academically disqualified following the completion of the fall
semester and are no longer enrolled in school, according to sources.

Joseph, a cornerback, and Rowe, a fullback, are sophomores
and were also teammates at Poly High. They were eligible for the Rose
Bowl because grades were not officially posted at that time.

Too bad cause both players were solid contributors on special teams.  Best of luck to both of them; hopefully they can work hard and get readmitted.
