The NCAA is in the process of reviewing the academic records of Maryland freshman guard Sam Cassell Jr., a person with knowledge of the situation told The Post.

The issue surrounds Cassell’s “initial eligibility” to become a student-athlete at Maryland, the person said. There is no expected timetable for the decision, but this development calls Cassell’s status with the men’s basketball team into question.

The news was initially reported by InsideMDSports, citing “multiple prep coaches with knowledge of the situation.”

Cassell had already been admitted into the University of Maryland, so this is an NCAA-related issue that arose after the fact. It is unclear whether Cassell is currently enrolled in classes this semester, and Maryland officials declined to comment on the matter.

If Cassell, a 6-foot-4 Baltimore native who attended prep school at Notre Dame Academy in Fitchburg, Mass., is ruled ineligible by the NCAA, that would remove him from a back-court rotation that includes Nick Faust, who was tops among current Terrapins players in points and assists last season; Pe’Shon Howard, whose 2011-12 season was ended by a midseason knee injury; freshman Seth Allen; and Logan Aronhalt, a transfer from Albany. Transfer Dez Wells could also play a role, provided that the NCAA approves Maryland’s request to waive his two semesters of mandated ineligibility because of the NCAA’s transfer rules.

More on this as it becomes available.
