USC defensive tackle Noah Jefferson will transfer from the program, Jefferson said on Tuesday. Jefferson, a sophomore, played in the season-opener against Alabama but has not played since.
When he returned late in September, Helton said "We're always going to put academics first and make sure he's fully healthy."
He added: "I know he's chomping, ready to get back and everything, and be right."
Jefferson has not practiced with the team since his absence.
