Karviar Shepherd, the prized recruit of TCU’s incoming basketball class, has been ruled ineligible by the NCAA because of academic issues related to his high school, Dallas-based Prime Prep Academy, TCU coach Trent Johnson said Thursday.Shepherd must go through an appeals process in an attempt to save his freshman year. His Prime Prep teammate, LSU signee Jordan Mickey, has also been ruled ineligible.The players are “non-qualifiers,” meaning they did not meet the academic requirements for NCAA Division I athletics. Non-qualifiers are ineligible for an athletic scholarship and are not allowed to practice or compete during their first year.“These kids are going to have to go through the NCAA, so it’s all real premature, in terms of saying they are going to be ineligible for their first year and all that,” Johnson said. “To my knowledge, it’s in the NCAA’s hands and there’s an appeals process they are going to have to go through, and that’s pretty much it.”Shepherd, a 6-foot-9 center, ranked 77th in the class of 2013 by ESPN Recruiting Nation, is on the TCU campus and has completed a summer school term, Johnson said.Shepherd transferred to Prime Prep for his senior year, after his coach at Arlington Grace Prep moved to the charter school founded by former Dallas Cowboys star Deion Sanders.Shepherd played his first two years of high school basketball at DeSoto.Prime Prep Academy announced in January, via the school’s website, that its curriculum met NCAA guidelines. However, the NCAA Eligibility Center says on its website that Prime Prep is under “an extended evaluation period to determine if it meets the academic requirements for NCAA cleared status.” The NCAA requires athletes to have completed 16 approved core courses before high school graduation, 10 of which must be completed before the athlete’s seventh semester. The requirements include four years of English, three years of math (Algebra I or higher), two years of natural or physical science, one year of additional English, math or science and two years of social science.Representatives from Prime Prep Academy, including Sanders, the school’s superintendent and head basketball coach, did not return calls requesting comment.
