LSU officials say they've submitted a response to NCAA questions they received in December about the university's internal probe into allegations of improper contact between a former player and former assistant coach. The NCAA has told LSU that it did not find any violations beyond what the university reported a year ago, but did have questions. LSU issued a release yesterday stating it responded in a 126-page document that the NCAA's infractions committee is expected to consider during its April 15-17 meetings. LSU did not reveal specifics of the documents. The probe concerned receivers coach D.J. McCarthy, who resigned in 2009, and lineman Akiem Hicks, a juniior college transfer who never played.
