SMU sophomore Keith Frazier is the latest member of Larry Brown's program to be sidelined by academics and will not play again for the Mustangs unless an against-the-odds appeal is somehow successful, a source confirmed to CBSSports.com on Friday.

A source also told CBSSports.com this development is part of a larger issue.

ESPN.com reported early Friday that Justin Martin's recent departure is too related to academics, and sources have told CBSSports.com that last's week's news that assistant Ulric Maligi, a heralded recruiter, has taken an indefinite leave of absence for "personal reasons" is less about "personal reasons" than it is about this possible scandal that sources told CBSSports.com the NCAA is investigating. In fact, a source confirmed to CBSSports.com on Friday afternoon that the NCAA has sent SMU a notice of allegations that includes allegations of academic improprieties, which was earlier reported by ESPN.com. One source also told CBSSports.com that among the issues is a questionable transcript, and that the odds of Maligi ever returning to SMU are "slim."

SMU subsequently confirmed that it has received a notice of allegations.

Maligi recruited Frazier to SMU.

SMU is 13-4 overall, 4-1 in the American Athletic Conference.

The Mustangs host East Carolina at Moody Coliseum on Saturday.
