According to the source, the difference between the Riek and Sidney cases is that a specific violation has not been identified. Riek was suspended for amateurism violations. Sidney is being questioned for how he and his family supported themselves while living in Los Angeles for two years after the family moved there from Jackson, Miss., for high school.</p>
The source said the NCAA has not identified a violation but is sitting him at this time because of the suspicion of a violation. Mississippi State, which declines to comment on the matter, won't play Sidney unless he's cleared to compete. The fear is that games he participates in will be vacated if he's ultimately ruled ineligible.</p>
